Silly question - Week 4 or 5? 17DPO

[Nightbeforeslothmas]

Would appreciate a bit of help as very new to trying & had a bit of a shock getting 1st time lucky. Naiively thought test are supposed to show 10-14 days DPO (it showed 16dpo after 2 failed clearblue earlies 7 and 14 dpo and also daily amazon pink dye tests since 8dpo). Learnt lesson, don't write yourself off at day 14 or trust clearblue early results..

What 'doctor' week of pregnancy am I in today at 17DPO?

A website said it's 5th week.. I'm 4 weeks and 3 days since LMP

So I am in 5th week now right?

I do it since last LMP which is the ‘doctor’ weeks. I’m 19dpo and currently 5 weeks and 1 day.

@cosymama2020 thanks! And congrats/good luck

So 4 weeks and 3 days since LMP.. does that count as 4th week in Doctor terms or 5th?

As 4 weeks on the dot since LMP would be say, thurs just gone.. then next Thurs would be 5 on the dot.

So guess where I am getting daft & confused is whether the Dr's 5th week starts from the day of the 5th week anniversary or after the 4 week mark 😅

You’d be 4 weeks 😊 then for example if you’re 5 weeks and3 days you’d be 5 weeks.

Cheers!
