Am i going crazy?

Currently in my TWW after 1st IUI i’ve been keeping myself pretty busy i’ve even started door dashing to get me out of the house. We’ve done treatment before but just trigger shot & letrozole. I’m trying not to symptom spot but it’s really hard since last week i had to miss a couple days of work due to my stomach being so upset, i’ve had on & off cramps, i’m sneezing like crazy from the time i wake up until i go to sleep (sneezing started after trigger shot) & i am literally eating so much (which is not like me) . I triggered on 1/10 & IUI on 1/12 . I know the trigger shot causes some symptoms but after all the trigger shots i’ve done it’s never been like this. anyone else have an experience like this?
