after being on oral birth control for 10 years (I'm 30 now), my husband and I have been trying to get pregnant using opk but no luck so far. every month I get 2 positive opk tests exactly when I should, we DTD the entire week of possible fertility, but still aunt flo arrives. I've heard that evening primrose and probiotics can help with cervical mucus and vaginal health. any success out there or other suggestions?
