For me, when its my period my breasts hurt on the outside. Anytime I've been pregnant they've been tender on the insides close to my sternum.

For me they just feel bruised but I’m still only a month along and they’re getting worse

It was just sensitivity.

@Luna in your 2nd tri was it because they were growing and couldn't fit bras or was it because they were just sensitive? I don't remember mine being sensitive with my first but they did grow and refused new bras I would only wear for a couple months, so I mostly went braless

I don't get it until almost my second trimester, and then it pretty much is where wearing a bra is not going to happen unless absolutely necessary. I get the "fuller" feeling you described in early pregnancy.

Hmm never experienced that before

like a sore achy feeling where taking off your bra is uncomfortable . Feel heavy and just sensitive really. It’s a pain in the ass lol
