I'm confused 😕🤔

I'm ttc since 2 years .. last year I had one chemical pregnancy.

This cycle is letrozole supported, took dydrosterone as well..

Today is CD 31 , ovulated on CD 13 ..

I'm taking so many tests since last 2/3 days ..

Some tests is giving faint line , some giving nothing.. what to do .. I'm just worried if I'm having another chemical this cycle as well .. today I'm having little abdomen cramps ..
