6pdo and hurting.

I’m 6dpo, and experiencing period like cramps. My boobs are sore too (which they do a week before af anyway) but my stomach feels extra bloated & (tmi) I’m constipated which rarely ever happens. So uncomfortable I can’t sleep at alllllllll

Could this just be af trying to show early??

(I have PCOS and took my first round of Clomid this month)
