I was on topomax 25mg twice a day everyday for awhile for my migraines. I weaned myself off because I want to try to conceive again. I have been off for 15 days. I am fixing to ovulate does anyone know how long you have to be off topomax before trying to conceive?! How long is the minimum you have to be off? I really want to try this next week since it's my ovulation window but worried I haven't given the drug enough time to be out of my system!
