help 😩

Danielle
Last month I took progesterone & Femara like my doctor ordered. I had a period, not quite sure if I ovulated.  
I had Walgreeens brand OPK and I read a lot of reviews after trying them & people were saying they ovulated but the Walgreens OPK said negative.  & that's what happened to me, everyday was a BFN.  
I went to my doctor for a follow up & he says I most likely didn't ovulate. & now wants to try another round.  
My period is over 2 weeks late.  I don't want to start another round if by some chance I'm pregnant. We had a lot of sex especially on my most fertile day.  
Has anyone had this problem? I thought if you had a period, you ovulated.  
Any advice helps.Â
