I have a question in regards to meds and menstrual cycle. I took Keppra for one month and have now been off it (currently med free) for 3 months and I've noticed my cycle is out of whack, which is not at all normal for me since it's usually like clock work. The 1st month it came almost 2 weeks early and now I'm really late (I should've had it August 18, 19, 20 or so (mid to late August and it's now mid September). I'm actually trying to get pregnant and took a pregnancy test but it showed negative and now I'm getting a little concerned since I will need my menstrual cycle if I want to get pregant. I'm assuming since I've been off now for 3 months my body should be bouncing back, but some side effects are still lingering. Has anyone's cycle gone out of whack due to the meds? Although I question the Keppra since that's what I was taking I would assume if one has the potential to cause this problem they all do. THANKS!
