Menstral Cycles and Medication

I am taking the following medications: topomax (topamax) 50 mg, klonopin 1.5 mg, lexapro 20 mg. Will this cause interferrance with my menstral cycles? I've been on the topomax (topamax) a little over a month now, and have been on the lexapro and klonopin since August. I haven't had a period since October and while I haven't tested for pregnancy, it is highly unlikely that I am. I am 33 years old.

I only looked up the klonopin and it did say it can cause menstrual problems as a side effect.  I didn't check the rest on your list.  

But if you've had any "fun" this month still wouldn't hurt to get the pee stick.  Not sure which way you want it to be but hope you get the answer you're looking for.
