Sore ta tas

Aishiah

So my ta tas have just become super sore and firm. My last cycle was during V Day. My fiancé keeps insisting it’s pregnancy even though I’ve taken a test which proved negative. (I don’t think I’m preggers) he keeps trying to get me to go get blood work, is that necessary? Could there be other explanations? *I typically don’t get sore breast before during or after my cycle, only sore nips.

TIA
