I’m so nervous! Line eyes!

So I did my first iui cycle (letrozole-ovidrel250-progesterone vaginal suppositories) (triggered 7/25, iui 7/26 and again 7/27) after trying at home for a year and being diagnosed with nccah but I’m asymptomatic. Anyway, I was testing out my trigger shot and it looked like it had faded away yesterday which was 10dpt/9dpo but now this morning 11dpt/10dpo the line looks darker!! Am I going crazy?! I don’t wanna get too excited yet but I’m so nervous this will be my first time ever being pregnant. For the past few days every time I eat something my stomach starts hurting really bad the only thing I can eat without feeling like complete crap is pizza.
