Axillary Breast Tissue?

Whitney • My 🌈 is 3 years and my second is 16 months 💕 1 loss

Has anyone else had this issue pop up during pregnancy? I developed a lump in my armpit that they took an ultrasound of and turns out it’s breast tissue.

Apparently very common and nothing to be concerned about, but curious if anyone else has experienced this since pregnant? And if it’s resolved itself afterward (I am hoping for that!)?

Can pregnancy get any weirder lol...
