24 weeks and strange hard areas on Tits.

FTM here and I’m 24 weeks Tomorrow. Last two three weeks I’ve had these hardened areas on my boobs on both on the inner parts some in the ariola area aswell. It’s just hard almost feels

And looks like a massive mosquito bite. I’m guessing it could be some sort of milk build up or who knows because I don’t! Has any of you ladies heard of this or had this during pregnancy? Let me know what’s going on here!? 🤔🤣😆

About to get my husband to do the check as he calls it. Lol somthing like this. But tonight I’m gonna show him the area see what he thinks. (Probably not much while staring at my tits lol) since getting pregnant they are huge either of us can get over it. I was pretty small ALWAYS ! Well not totally flat but most definitely b cup.
