Almost Everytime I'm about to start my period my nipples get crazyyyy tender/sore. But this month they started getting sore really early?? I'm talking like two weeks before my period is scheduled to start? I'm supposed to start next week, and I can feel it coming and all that, but <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> also says my fertile window ends in 4 days, so I was wondering if that could have something to do with my nipples being so sensitive? Has anyone experienced this before? Or does my period just reallyyyyyyyyyyy hate me this month.🙄
