How many weeks am I?! So confused

[LaceyLou42]

I know I conceived on the 24th of August, because that’s when I ovulated, and we hadn’t BD’d for a good while before then and all previous tests were negative. I got my BFP 2 days ago, which was 15dpo. So technically I’m 2 weeks pregnant? But when I use online calculators it tells me 4 weeks? Help!

You count from the First day of your last period .

Congratulations!

It goes from the first day of your last period, so you are 4 weeks

My last period was the 10th of June which was just a withdrawal bleed after coming off the pill. I hadn’t had a natural period at all, I took 77 days to ovulate so I’m still confused :( in which case I’m a good few weeks pregnant?!

Pregnancy is dated from th first day of your last period, NOT when you conceived.

Go with the 4 weeks thing.
Your super long cycle has confused things, but yes, you were2 weeks pregnant on the day you conceived!

In the UK, 2 weeks are added so if you get a positive HPT on your period due date, you're 4 weeks pregnant. 2 weeks is based on a 4 week cycle and ovulating / conceiving smack in the middle of your cycle

As PP says it is dated from LMP until you have dating scan and from that point forward it is based on those measurements which can be a week or so either side of LMP. Even the conception date isn’t certain as sperm can live for a week so you've actually got no idea when the egg fertilised, even if you know when you ovulated.

In the UK, 2 weeks are added so if you get a positive HPT on your period due date, you're 4 weeks pregnant. 2 weeks is based on a 4 week cycle and ovulating / conceiving smack in the middle of your cycle

Thanks! I’ll stick with the 4 weeks for now!
