@Denni ahh ok. See for me it doesn’t make sense because I know the conception date!
Implantation can take up to a week after conception. So it's about right. Copied the below of Dr Google 😂 Implantation typically occurs 6 to 12 days after ovulation, or around 10 to 14 days after conception. The exact timing depends on when ovulation occurred and if conception happened early or late in the ovulation window.
I wouldn’t worry about it. The scans give you a ballpark month that the baby is due. They use the size of the head to “date” it. My first had a big head so it totally screwed up his dates by two weeks!!
I went for a scan thinking I was 6 weeks but was showing 4 weeks at the scan, made sense as I was on the pill so my last period wasn’t really a period
