NEW TO TTC VERY CONFUSED

So I’ve been doing OPK testing I use Premom I thought I got my peak Monday so I had sex Tuesday and Wednesday.

My bbt Wednesday was a 98.2 Thursday 98.1 Friday 98.0

I tested today and my numbers have gone up (1.36)

Was Monday not my true peak?

Was having sex Tuesday and Wednesday not count ?

I am getting my tooth removed today so it might be tough to have sex
