Question: Can Topomax hinder my birthcontrol
|Iluvpolkadot89 - Sun May 31, 2009 9:31 am||
I has sex about 3 days before I started taking Topomax, I am on birthcontrol and we did use a condom , but I have missed my period since starting mymigraine meds, and I have taken the at home pregnacy test and they have all said neg. Could my new meds be the cause of the no show period?

You did not indicate how far overdue your period is but even so it can be very difficult to identify the cause. Topamax itself is not likely to affect your cycle but everyone at times, experiences missed periods for no apparent reason. Birth control pills themselves often alter your periods, often making them much lighter and some types result in complete cessation. If this was the type you were using, you would have been informed of that effect, however.
Tompamax can possibly decrease the effectiveness of the pill as contraception so it's best to use a second method, which you have indicate you have done (condom). With both contraceptives in place, pregnancy is very unlikely, so I would probably believe the HPT results. Chances are your period will arrive late or at least resume next month, but there are some rare cases of pregnancy in spite of even two reliable methods so another test might be in order if you don't start your period next time around the expected time.
I do hope this helps you with your migraines. Try not to stress too much about this, as stress and worry are also known to delay periods. Missing them is not harmful to you in any way; just causes you to worry about pregnancy.
