I usually start menstrating on the 1st of the month .unfortunately today is the 14th and still nothing .I haven't taken a hpt because I have to take meds daily for seizures and other health issue that I thought could mess up the rsults but I don't know if I'm pregnant or on too much meds please help

How often are you late, do you miss periods sometimes. Have you just started the meds.

You should test.

The pregnancy test tests for one hormone only, and it's a hormone that's only produced when you're pregnant. Nothing else causes it. Your meds shouldn't be a problem when you're testing.

Try a test tomorrow using first morning urine. If it's negative, wait and see what happens with your next period. If you miss it as well, test again or get a blood test done.

Good luck.
