I took a preg. test this morning the first morning after my missed period and it was negative. Just wondering how accurate is it after only one day passed missed period.
Most test say that they are 99% accurate the day of your missed period, however, some women may not have enough hCG to register a positive result that quickly. I would wait a day or two (since it takes 2-3 days for your hCG levels to double) and test again. Buy a test that is very sensitive, use the first morning urine and cross your fingers.
Good luck!
If you still get a negative, then you may want to wait a few more days or go and get a blood test. For some reason, some women get negative test well into their first trimester, so a blood test may be an option.
I am 2 days overdue and I repeated that test twice (two tests in one package) both came out exactly the same way. The minus sign was fully there and only the outlines of the plus line turned blue, and had no color in between. Is that an evaporation line? The result turned that way right away, well as soon as I it cleared enough to read it..The control line took 5 minutes with both tests to fully develop.
The HCG hormones are stronger (most condensed) in your first morning urine.
But, as the other gals have said…go to the doctor for a more accurate result. They can do a quick blood draw, and tell you with all certainty that you are pregnant or not.
If you want to try another HPT before hitting the doctor’s office, then try again using first morning urine… Wait a couple of days and repeat again.
If you are pregnant now, you will still be pregnant in a day or so…it might just be too early to appear clearly on a test.
What are the diff types of water pollutants?
Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, groundwater).
Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging either to individual species and populations, but also to the natural biological communities.
Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds.
Causes of water pollution
The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese, etc.) the concentration is often the key in determining what is a natural component of water, and what is a contaminant.
Oxygen-depleting substances may be natural materials, such as plant matter (e.g. leaves and grass) as well as man-made chemicals. Other natural and anthropogenic substances may cause turbidity (cloudiness) which blocks light and disrupts plant growth, and clogs the gills of some fish species.
Many of the chemical substances are toxic. Pathogens can produce waterborne diseases in either human or animal hosts. Alteration of water’s physical chemistry includes acidity (change in pH), electrical conductivity, temperature, and eutrophication. Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases in the primary productivity of the ecosystem. Depending on the degree of eutrophication, subsequent negative environmental effects such as anoxia (oxygen depletion) and severe reductions in water quality may occur, affecting fish and other animal populations.
Pathogens
A manhole cover unable to contain a sanitary sewer overflow.Coliform bacteria are a commonly-used bacterial indicator of water pollution, although not an actual cause of disease. Other microorganisms sometimes found in surface waters which have caused human health problems include:
Burkholderia pseudomallei
Cryptosporidium parvum
Giardia lamblia
Salmonella
Novovirus and other viruses
Parasitic worms (helminths).
High levels of pathogens may result from inadequately treated sewage discharges. This can be caused by a sewage plant designed with less than secondary treatment (more typical in less-developed countries). In developed countries, older cities with aging infrastructure may have leaky sewage collection systems (pipes, pumps, valves), which can cause sanitary sewer overflows. Some cities also have combined sewers, which may discharge untreated sewage during rain storms.
Pathogen discharges may also be caused by poorly-managed livestock operations
Chemical and other contaminants

Organic water pollutants include:
Detergents
Disinfection by-products found in chemically disinfected drinking water, such as chloroform
Food processing waste, which can include oxygen-demanding substances, fats and grease
Insecticides and herbicides, a huge range of organohalides and other chemical compounds
Petroleum hydrocarbons, including fuels (gasoline, diesel fuel, jet fuels, and fuel oil) and lubricants (motor oil), and fuel combustion byproducts, from stormwater runoff
Tree and bush debris from logging operations
Volatile organic compounds (VOCs), such as industrial solvents, from improper storage. Chlorinated solvents, which are dense non-aqueous phase liquids (DNAPLs), may fall to the bottom of reservoirs, since they don’t mix well with water and are denser.
Various chemical compounds found in personal hygiene and cosmetic products
Inorganic water pollutants include:
Acidity caused by industrial discharges (especially sulfur dioxide from power plants)
Ammonia from food processing waste
Chemical waste as industrial by-products
Fertilizers containing nutrients–nitrates and phosphates–which are found in stormwater runoff from agriculture, as well as commercial and residential use
Heavy metals from motor vehicles (via urban stormwater runoff) and acid mine drainage
Silt (sediment) in runoff from construction sites, logging, slash and burn practices or land clearing sites
Macroscopic pollution—large visible items polluting the water—may be termed "floatables" in an urban stormwater context, or marine debris when found on the open seas, and can include such items as:
Trash (e.g. paper, plastic, or food waste) discarded by people on the ground, and that are washed by rainfall into storm drains and eventually discharged into surface waters
Nurdles, small ubiquitous waterborne plastic pellets
Shipwrecks, large derelict ships
Say if you decided to change two different things in the experiment and you got a result that you liked and wanted to document… how would you know which of the things you changed was the cause of the positive result? If you change only one at a time you know what caused the result.
Many home improvement websites recommend using 15-pound felt paper as flooring underlayment. I wonder if it will release Volatile Organic Compounds into my house over time.
After much googling this issue does not seem to be addressed anywhere.
Will the felt paper have a negative effect on my indoor air quality?
Its typically impregnated with TAR and has a strong bituminous odour.
I m guessing that your talking about under a hard wood flooring. Your encapsulating the felt so even if it did release any thing into the air under exposed conditions, you have it trapped and it cant and doesn t anyway. It always used under hardwood to both use as a moisture barrier and to prevent direct wood to wood contact and cut down on noise.
If your doing a prefinished hard wood, many manufactures approve of a plain rosin paper as the layer under the wood.
Laminate never has either of these papers under them . Its a different under layment altogether. Any questions you can e mail me through my avatar. GL
Otherwise, you have no idea which variable change affected the result. Did the plant die for lack of light? Or because you also cut off its air supply? Or put it in a closet full of mothballs? Or put it in reach of the cat who tore it up? Or put it out of sight so you forgot to water it?
I would like to know what the various causes of air pollution are, especially in relations to the hotel industry.
burning fossils, rice paddy field and cows- methane, cars etc
The tree had only one apple
A bright red apple
I reached up to the apple
and took it in my hand
The apple spoke
It said " You have stolen an apple."
I let the apple fall
And God ate it.
This is a epanorthosis poem written by C.K Bissel. It is called "Adams Version"
i was just curious as to what this poem conveys to you.
this would seem to be the adam and eve story ,and god going against his own law
Sum from n=0 to Infinity of: [sqrt(n+1) - sqrt(n)].
Without rearanging the above series at all, and without multiplying top and bottom by [sqrt(n+1) + sqrt (n)], is it possible to apply the Integral Test to determine if the series is convergent? If there is some reason you cannot use the Integral Test without first multiplying the top and bottom by [sqrt(n+1) + sqrt(n)] please explain WHY. If the Integral Test CAN be used without manipulating the series at all, please show the steps to get the answer as to whether it converges. Thank you.
This is an interesting question. I’m going to say no.
If you do the integration, you essentially get (disregarding constants) infinity minus infinity. We would need to use some additional limit process to know whether this evaluates to infinity, zero, or negative infinity. So if we are completely restricted to the integral test, I’d say we cannot conclude that the series converges or diverges.
My car needs an emissions test this year, but will it pass if the engine has a bad bearing on it? I know it’s a bad bearing, because after a few minutes of driving the car, it starts to make this strange wailing noise.
assuming its a bearing, IF it even makes it to etest, that shouldnt affect the outcome of the test but you should get that fixed it could let go at anytime
