Should I keep testing? Since I think I ovulate late!

I took provera to get my period I started on January 5th for 10 days I finish on the 14th I got my period on the 17th and then I started with letrozol for 5 days I finish with letrozol on the 24th. I started testing for ovulation I got the peak on February 5th.

I had intercourse on the 2th and the 6th and 7th.

A week after I had cramping on my left side.

I’ve been doing the pregnancy test since last week is been coming negative. I’ve been having very sensitive boobs.

I’m very confused. Today the 19th is been already 2 weeks that I ovulate.
