How many weeks am I?

[Mumof3cheeky]

Im a usual 30-31 cycle with ovulating around day 16-18
I had the one off cycle ovulating on cd8-9 and now have bfp
How would I work out how many weeks as my usual cycle is 30-31 but obviously this one would not have been if I hadn't got a bfp🤔

Some due date calculator let you put in date of conception, like yourduedate.com it will tell you how many weeks you are and all the milestones.

Thank you

I'm not 100% sure if this is correct, but as a rough calculation i think you could count 38 weeks from conception?
That's interesting you ovulated so early that cycle, i'm usual 30 day cycle and ovulate around day 18 but opks didn't pick up ovulation last cycle, i thought probably just didn't ovulate but wouldn't of been testing as early as day 8/9 so after you saying that i now wonder if i could have missed it.

Thanks merz sorry it's tmi but my af was finishing at cd7 and noticed lots of ewcm on tampon so started testing and 2 days later it was+ Good luck x
