hello I have been TTC and I have a 11 month old that I bf . So I don't get af or ovulate so I started taking maca, vitex and epo.. Well today I decided to take a CB and it was a flashing smiley face. But my opk was negative. I have been taking maca and vitex 8 days today and epo for 2 days.. Also started fertile cm pills. My question is are the CB accurate? The opk is negative. And when should I test with the opk again.. I am so confused could it be that I am gearing up to ovulate? thank you
