A bit about me. I've been married 9 months, with my husband since I was 26. Ttc since Jan but on the BCP for 8 years and took me 6 months to get a normal AF. now on Cd28 but had a positive opk that late in a cycle. V worried that might have an on baby, as heard late ov is bad. Confused and sick of POAS.!!!
