Well. According to my ultrasound we're 9 weeks along. I though I was 10w4d, based on my LMP. I mean, I now when I conceived. Which was July 26. & I was due for a period on the 2. Which leads me to believe I must've ovulated later. Idk. I saw the baby, and a healthy heart rate of 177. I'm just confused at how differently the dates were. Has this happened to anyone?
