My cycles have normally been 36-37 days and I usually ovulate at around cd 21-22. I have been testing since cd 15 just to be sure I didn't miss it and had still not yet had a positive ovulation test. Today on cd 30 I finally got a strong positive but am worried that this is too late for successful implantation. My period is due to begin in a week. We will still bd for the next few days but just wondering if anyone has had this happen and had a healthy and successful pregnancy? Thanks! *fingers crossed*
