Can my bra make my breasts sore?

Hi ladies! For the past(almost) week I noticed my boobs were feeling a bit sore. I’m in between my cycles, and it’s not as intense as it usually is right before I start my period. I started noticing also the past month that my bra has been a bit snug, not the cup but the waist part. It hasn’t bothered me, until my boobs started getting a little sore, especially on the outer side near the side of my body(right below my arm pits). I should mention that I am sexually active and ovulating, but I’ve been pregnant before and my boobs were EXTREMELY sore, not this mild.

Could it be the bra, or something else??
