awful breast tenderness

Megan
Ugh I'm on a low dose birth control pill, I take it perfectly. The last time I had PROTECTED sex was the beginning of October so I'm not pregnant as I'm had two withdrawal bleeds since then...
This is my fifth month on the pill and this month is so much different than previous months. Not as much discharge, no mid cycle spotting that I've had the last two months, and one annoying thing 
EXTREMELY BAD BREAST TENDERNESS
Has anyone else experienced this?😩if so what do you do for it?
