Hi there,
I know I will find this out at my dating scan but thats not till 20/04 (eeeek) and I am impatient 
and also its useful to know roughly how many weeks I am as each week feels like a little milestone!
So, I'd been on the combined pill for 15 years and finished the pack on 14/01 - had my withdrawal bleed 19/01 - 22/01 and then didn't restart my pack.
Took a clear blue digital test on 17/02 which was bfn then on 18/02 and 19/02 had very very mild brown spotting, only noticed when I wiped (implantation maybe?)
I then took a FRER on 25/02 and it was positive - the line came up immediately and was darker than the control line. I took a few more tests that day and on 26/02 and same thing - immediate positive and strong line.
Since my LMP was 19/01 but wasn't natural and was a withdrawal bleed that puts me at 6 weeks however surely if that was the case I would have got a bfp on 17/02 as that would have been enough dpo as would have ovulated week commencing 31/01?
Therefore it seems more like i ovulated w/c 07/02 (probs in the first half of the week) to get the positive when I did making me 5 weeks roughly?
I doubt it would have been as late as w/c 14/02 to get the positive when I did which would have been max 9dpo - the line looks too strong for that.
Sorry for the long rambling post 
just want to kinda work out the weeks! Looks like it might only be a week out from LMP potentially?
Thanks in advance for anyone's input
