What the hell is going on with my boobs ??

Before my period I get sore swollen boobs. They usually disappear within a day or so afterwards and go back to normal.

I had my period like a week ago and my boobs still feel like PMS boobs.

Took a pregnancy test about 5 days after I’d finished my period, just to be on the safe side even though I know it was a full on period not anything like implantation bleeding - test was negative.

No other symptoms just heavy sore boobs like I’m due on?!

Last time I was pregnant my boobs /nipples murdered me and they went huge - this time it just feels like PMS and I don’t feel like it’s anything to do with a pregnancy at all.

Am coming up to 41 years old, never bad this before…

I’m at a loss. Any ideas?
