Bfp but timing worry, girl sway

So being as i only bad one montj of clomid i didnt want ro mess around and as clomid gave good results i thought maybe frequency would not hinder my sway but npw im worried. So i bd cd11 , cd14 and cd16 and either ovulated on cd 15 or 16... i got a pos opk morning of cd15 but then negative by early afternoon . This either meant i dtd 5 or 4 days before ovulation and also 1 or 2 days and 1 day after or day of. Worried that this was too many attempts for girl sway to have a chance and i stuffed it up. ??? I feel lile i would have ovulted cd15 due to neg opk in evening and having symptoms which also continued through to next day.

You can't tell when you've ovulated on the basis of O pains or when OPK goes negative. Those things do not help pin down O to the day, I'm sorry.

CD 11 attempt almost certainly did not count. So even in the worst case you would have been in with 2 attempts (which I would have SUGGESTED you do on the Clomid anyway since you only had the one month!)

I know it's hard but please don't worry, ya done good.
