Hey ladies my first period since discontinuing Depo Provera was February 16th was very heavy and lasted 6 days, my Ovulation day was March 2nd in which my Husband and I had sex the day before and after this day, and have continued to about twice a week up until this point. I took my first Clear Blue Digital test March 18th and it was negative, today I am now 7 days late when should I retest?
