Itchy Breast 😩

Jameika • Hi, I`m 20 years of age ! Me & my lovely fiancé have been trying to conceive for a little over 6 months now!
Okay , so , the day before yesterday & last night my breast have become really itchy . I have these little bumps above my nipple & areola & they feel like little tiny hair bumps . They're really small & brown . When I scratched them , my breast became really hot . Has anyone had this before ? If so , what is it ?
