19 dpo ...

I’m currently 19 days past what I would say the day I ovulated. I got my positive opk day 30 and now I’m on day 50.

I can’t understand what happening, because if I’m not pregnant I should have gotten my period already ?

Last month I got a pos opk on day 40 and my period started day 54

I tried a HPT on dpo 16 and it was negative. I’m tired of Peeing on sticks
