This might sound really thick, but i can't figure it out. My last period was 12/12/18 i had a positive ovulation test on the 28th which means baby would be 5 weeks, but 7 weeks pregnant with period. I went for a early scan Friday due to bleeding which baby measured 6 weeks 1 day. This would mean i ovulated on the 20th! How does this work? I aslo didn't BD around the 20th only around 28th when i was ovulating. I cant work out when i conceived, surely baby wouldn't be measuring bigger than it should at this stage. Im really confused and can't figure it out😶
