I just had my first <a href="https://glowing.com/glow-fertility-program">IUI</a> on Tuesday! Exciting!!! I am currently on the progesterone supplement endometrin and TMI my nipples feel like they're on FIRE!!! They are so so sensitive and painful!! God forbid if I get goosebumps or a little cold, they feel like someone took a match to them!! Has anyone else experienced this??
