Wow I personally feel this is TMI but I see women talking about it frequently on here but WOWZERS are my nipples on fire this week!! I'm not even due for my period until the last day of the month and even though we are ttc I don't want to get too ahead of myself with hope but this isn't something normal for me either. I usually experience breast pain right before I get my period but this is just my Nipples and the best comparison I can give is when you wear a rough-textured shirt without a bra and feel raw. Even more tmi I'm sitting in my living room with my boobs out of my tank top bc they are THAT sensitive!!  I hope this is for good reason but I hope I don't get my hopes up too much either bc I didn't think effects could happen this fast...
