Long story short, I had a fling with a friend on Mar 2. Told me she was pregnant after taking an hpt on mar 29. First doc appointment was on May 2 and put her at 7 weeks 4 days after looking at ultrasound. Doc gave EDD of Dec 15. I've used every conception calculator I could possibly find online, I've manually counted, I've used naegele's rule too, and nothing adds up. Everything puts conception date on or around Mar 24. Should I be worried? Any help or info would be greatly appreciated. I would like to be excited but I'm very confused right now.
