Need some insight please !!! Ftm and my breastbone has been hurting for like a week so now I am struggling wearing a bra because it pushes right into it.. I've tried sports bras (still pain) tried reg bra (still pain).... I'm running out of options!!! Can't go braless at work lol.. didn't think my breastbone or whatever bone this is had anything to do with pregnancy until I researched it and it was saying how about this time in pregnancy your organs are moving around to make room. Now I already have small ribs (yes diagnosed) so could that be adding to the pain?? I just am not sure how to get relief
