That really! I'm 9+4 and today, after my shower, I noticed two, small, symmetrical, pronounced mole like growths near my armpits. Hubby is a doctor, did a google and we've concluded that these are growing along milk lines (look it up!)...he thinks I've probably always had them but the mental hormones are making them grow bigger/darker. They're called supernumerary or accessory nipples.
Apparently they can even secret milk..
So - now I know. Any one else? Or am I the only alien?
