Cori • Preggy with baby #1!!
I took off my bra today and I noticed I have a red like.. hole? Right above my areola... there is a picture bellow... any idea what it is? If it is still there Wednesday when I have my doctors appointment I was gunna show him but I'd sleep better knowing it's nothing.. I'm the kind of person who's worried about every little thing (ftm)
