I had a natural mc on July 22. at my two wk follow up appt the dr gave me the ok to ttc again. My hcg was 51. I started taking opks yesterday and it was negative all the way. My one today showed peak (clear blue digital- flashing face). I couldn't really be ovulating this early? Especially since a week ago my hcg was still positive? Should I take a hpt to be sure there's no more hormone in my system?
