Anyone have this tightness in between your breasts the lower part. I noticed the last week when my bra is off it almost feels like I’m wearing an under wire bra. Feels the same when I have my bra on. I have my OB appt on Tuesday, but it’s rather uncomfortable not sure if it’s my stomach still expanding at the top I’m 30 weeks currently but it’s becoming a bit painful at times
