Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more

Can my medications throw off a pregnancy test... Can you give me some sites that would help and show the meds that do.

Pregnancy test: Can other substances, such as medications or alcohol, interfere with the results of a home pregnancy test? Most medications, including birth control pills and antibiotics, do not interfere with pregnancy test results. The only meds that could cause a false positive are fertility meds containing derivatives of hcg. But no meds, of which I am aware, can cause false negative (i.e. Test neg but preg). ...Read more

What factors can contribute to a false positive pregnancy test?  I'm not on any medication and an curious if my positive result might be incorrect.

Do you think that i could get an accurate reading from a home pregnancy test while taking medication?

Do you think that i could get an accurate reading from a home pregnancy test while taking medication?

Yes: Most home pregnancy tests are highly accurate once you have missed your first period. Follow the instructions closely and use your first morning urine. It also helps for a more accurate method to collect the urine in a disposable paper cup and dip the test strip inside for the prescribed time vs holding the strip in the urine stream. Refrain from alcohol and cigarettes until you know for sure. ...Read more

Will my medication for tonsillitis and gastristis effect my home pregnancy test ? If it does effect what should I do to get accurate result?

Did you miss a: period? You should do a home pregnancy test only if you have missed your period by 4-5 days. You did not mention the medication you are taking, but it is unlikely that that will affect the results of the pregnancy test. Use first morning urine and follow the instructions in the package carefully. ...Read more

I am 7 days late on my period and I took a pregnancy test and it was negative but I'm on the medication ampicillin.  What should I do?

Could the medication 'divalproex sodium' or 'topiramate' affect an at home pregnancy test result cuz im 5 days late and it's negative i'm never late?

Could the medication 'divalproex sodium' or 'topiramate' affect an at home pregnancy test result cuz im 5 days late and it's negative i'm never late?

Trust the test: Home pregnancy tests are very accurate and this medication will not affect the test. They are the same tests used in a doctors office. They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. If you doubt the result you can repeat it in 1-2 days. If you were pregnant the hormone level would rise enough for detection. ...Read more

I took a cheap pregnancy test first thing in the morning and got a very faint second line (i took povacare medication for a yeast infection). I tested 2 first response pregnancy tests about 30 minutes after and both were negative. Am i pregnant?

Test again tomorrow: There is no really good reason to test multiple times in one day, IMHO. I suggest if you get an early test it makes alot more sense repeating the next day: then you can be pretty certain of your result. Good wishes. ...Read more

Missed 3 periods,negatives pregnancy test.Hyperthyroidism not currently on medications. Can hyperthyroidism cause a false negative, or stop ovulation?

Missed 3 periods,negatives pregnancy test.Hyperthyroidism not currently on medications. Can hyperthyroidism cause a false negative, or stop ovulation?

Hyperthyroidism ...: & hypothhyroidism, for that matter, can certainly affect ovulation. The thyroid really needs to function normally for healthy pregnancy & baby to result. I don't think there is anything specific about hyperthyroidism that would cause a false negative pregnancy test; typically an error in testing (imprecise following of directions) is to blame. Work with your doctor to optimize thyroid function. ...Read more
