Sore nipples but bfn so far?

Lora

Did our second IUI w/ clomid this time and progesterone suppositories like last time as well... last time I didn’t have sore nipples. I NEVER get sore nipple before or during my period, only when I’ve been pregnant before. BUT this month starting 8days past iui I’ve had crazy painful nipples, tested this morning 13days post IUI and negative. What gives?? 😢
