Q: Will recreational drugs or alcohol interfere with home pregnancy tests? A: Drugs such as cocaine, marijuana, heroine, and alcoholic drinks will not alter the result of a home pregnancy test, but it is better to test when not under the influence.

Litmus paper is used to test how acidic or basic a material is. Because gardeners often want to test the acidity of their soil, you can buy litmus paper in many gardening shops.

Yes. Many people cannot get a high enough hcg level to register on a home pregnancy test and need special blood work done to get a positive result.

about 3 to 9 days

No. Home pregnancy tests detect the hormone hCG, not byproducts of infection. Infections do not cause the hormones to be released. It is best to get the pregnancy confirmed by a doctor and have the UTI treated as soon as possible.

You can not become pregnant having sex while on your period. If you didn't have your period and you had sex and the urine test said negative, you most likely are not pregnant. If you still want to be sure, yes a blood test is more precise.

No not usually. Get to the hospital immediately. Definitely call your doctor and let them know what is going on.

Well I had the same thing and my pregnancy has been totally normal.That is why I didn't find out I was pregnant until I was almost 3 months along, because I thought it was a normal period. You should call your doctor just to be safe.

Hormones (estrogen, testosterone) can definitely affect pregnancy tests. For best interpretation of signs and symptoms alongside a blood test, see your doctor.

Most definitely, yes, you can have a false pregnancy test with tubal pregnancy. Hormones only know an egg implanted. Hormones do not know where the egg implanted.

It all depends. If you took the pregnancy tests too early, then you could get false negatives. I would recommend you wait a week, if your period doesn't start, then retest or get a blood pregnancy test at your doctor's office. ~pawsalmighty

no prednisone is a steriod that does not interfere with pregnancy tests.

I think it depends on how early you are in pregnancy. I took 10tests which all were negative even though I knew I am pregnant before the HgC levels were high enough to indicate pregnancy via test. You can usually get an accurate reading about 1-2weeks pregnant with a good test such as Clearblue digital (I used this which indicated I was 1-2weeks pregnant) and I'm not 4weeks pregnant and registered with the midwife. Good luck!

i was always told you will know when your pregnant, and it was about 6 days before i was even supposed to miss my period and i just had a feeling so i took a home preg. test, knowing it was too early, and it came back positive, with a very very faint line. about 3 weeks later i took another and it was clearly positive so i went to the dr and am 9 weeks pregnant now. so i believe it can be up to a week b4 u miss your period for some people, maybe not all. but if its coming up positive, you probably are prego

No. If you think you may be pregnant and your home test says different; trust your body. A doctor will do a blood test which will not only show right away; a 'quantitative' test can tell the level of hcG, telling about how long since you conceived. Which can be double checked with an ultrasound if necessary.

In very early pregnancy, yes. The reason it is recommended to take the test in the morning is because the hCG levels are more concentrated in the urine then, and can be more readily detected. So if it is in the first weeks of pregnancy, the level can go undetected.

yes. some pregnancy test show up negative, even though you are pregnant. I have the SAME problem with the EXACT same symptoms. I hope someone answers your question because I need help on this one too :(

The first three months while your baby is busy developing

Results are not considered accurate after that amount of time has elapsed. After 10 minutes it is said to disregard all results. If you still think you could be pregnant, then take another one in 3 days preferably with your first morning urine.
