Fertility med symptoms or preggers symptoms?

Please share your experiences, good or bad. I'm having a hard time not thinking my progesterone side effects are pregnancy symptoms. Rationally, I know sore boobs are from progesterone because they got that way just 1-2 days after my IUI, but I desperately want to believe there's a chance this pain is for a WAY better reason than a vag suppository, ha!!
