I know when you estimate your due date or how far along you are (if you don’t know what you ovulated or conceived), you do it by the first day of your last period. This is also how the midwives ask you up until you have your 12 week scan..
Going by that, I’d be 7 weeks today and I had a 30/31 day cycle. I’m so worried that when I go for my early scan on Saturday I’m actually going to be something like 5 weeks and have got it all wrong and be further behind when the midwife books me in for the dating scan.
It’s so confusing, I don’t know actually how many weeks I am because of not knowing when ovulation was..
