So I’m 23 weeks pregnant and 21 years old and I was feeling around my breast after taking my bra off and I found a round spot that isn’t hard but isn’t squishy and I can grab it (if that makes sense) its on my right boob near my armpit and is about the size of a quarter and I mentioned it to my husband and he swears it’s always been there and that there is one of the other side (I can’t find it).. i also found if I rub it it will shrink but will come back the next day and it’s beginning to be tender but that’s probably from me messing with it...you can’t see it looking at a mirror and I had a breast exam last year and the doctor didn’t say anything
