So I've taken about 10 OPK over 7 days after AF and I never got what they call a "positive" (which is two lines of equal darkness or test line darker than control). This is the darkest the line got. Then as I continued testing nothing would show up. Has anyone else experienced this? Was I really ovulation?ย
