I took an OPK on the last day of my period, the 19th, bc I had never taken one before. It said I was ovulating. I thought it was weird, but it was probably right bc I've been having extremely short cycles bc I got off the depo shot in September and everything is whacky. We baby danced then bc it said I was ovulating. Today, a few hours ago, I had a BM, sorry tmi, but I had the egg white consistency so we baby danced today. Are the opk's just faulty, or do people ovulate more than once, orrrr....?
