Counting pregnancy weeks - Emma's Diary App
Sorry - guessing I'm gonna be on this forum asking a LOT of questions as its my first time pregnant!! So I apologise in advance lol!
Basically I was wondering how people count pregnancy weeks, more specifically the Emma's Diary phone app. My LMP was 1/3 so my EDD is about 6/12 so this makes me 5 weeks 1 day pregnant (well 3 weeks since conception but doctors count it since first day of last period - right?)
Anyway, I downloaded said app, and it has my correct due date, but it says 6 weeks. I assume this is cos I'm in the sixth week of pregnancy, but the information about the developing embryo seems a week ahead. So I'm not sure if this is right? The dr's gave me the Emma's Diary leaflet and the app itself says done by some medical committee or other so I trust the info, just unsure about which week its placing me on.
As its my first pregnancy I would like to keep up to date with whats happening when etc, like when heart beats for the first time, when certain organs develop, and I'd hate to be a week ahead!!
So I guess what I'm asking is do I trust the app - which is currently saying 8mm in length - seems to far?!
If anyone can make sense of this rather disjointed post thank you!! I'm so confused!!
