I started using clear blue OPKs 4 days ago. The first night it was negative. I've tested every morning and all other three were the flashing smiling face. The solid smiley face means peak fertility. Should i get my peak soon? My cycles are always off. Usually 30-33 CDs. Any pointers? This may be TMI but my husband and I have been having sex one to two tokes a day for a week now. Surely that's good for pregnancy during the "flashing smiley face" period????
