I've never had sore breasts before my period was about to start and this week I've had it to a point where a bra hurts when I put it on. I'm 11dpo and This whole week has been miserable with them..I thought I was pregnant when I started having nausea, mood swings, fatigue and along with breast pain but I took two tests and both came up negative.... I'm supposed to start my period on the 31st of May ( in 2 days) My husband and I have a 5 month old already so we figured it could just be fatigue from having our little man but I feel like there's something else going on.. I'm so confused to what is going on with my body... help...
