Pregnant cd 21??

Hello everyone

I took clomid cd 3-7 , ovidrel shot cd 12 … I read somewhere that using a one step opk test can detect pregnancy ?

I used the opk on cd 20 and 21 and both positive. What could that mean?

With my last pregnancy 6 years ago I used the opk the same way, got 2 lines and eventually a positive pregnancy test day of missed period.
