I just finished my period yesterday. Started my opk today. Only took one though. I'm going to start twice a day as of tomorrow. Once around 10 am and then again around 3 pm. I'm supplementing with the liquid Geritol instead of prenatal vitamins this month. Heard it helps. Next month, if no luck this month, I'll do PreSeed, Geritol, and Fertile Aid all cycle along with my opks. After over a year, I'll try anything. My insurance doesn't cover fertility treatments and my pockets aren't that deep. Lol.
