The anatomy scan is Thursday

What is your guess? Below you see my chart. According to both the 6 and 9 week ultrasounds, the date of conception was CD15 (not 14). The positive HPT didn't come until late evening and was major squinter, so it's possible that was only 8DPO. I also had a very close to positive OPK on CD14, I just put negative because it was more positive the day before, and I've been known to see a slight thermal shift before O, so it's certainly possible that I O'd on CD15 and not 14, or maybe the egg was already waiting on the sperm. I'll let you decide
