Breast pain?

For the last month or so my breasts have been hurting so much. I get a shooting pain down the middle to the nipple. A few weeks ago on the side of my breast it was so tender, I couldn’t even lie on my side. It went away whilst I had my period and it’s come back on the other breast? It’s not like just ‘sore boobs’ or when I was pregnant. It really hurts 😩 any ideas on what it could be?

Also: I don’t know if it’s relevant but I’ve been cramping even though my period (which was short) was a week ago. I got a BFN and it’s not ovulation type pain. Could my hormones be going crazy?! I’ve been irregular the past 3 months, and I have no clue why 😩
