I am worried!! (Kinda tmi)

Cheyenne • This is my second pregnancy with a miracle baby.
I am 7 weeks pregnant and I just took my bra off (wearing a sports bra because it's more comfortable on my boobs) and I looked down and I have a giant red lump on one of my nipples. I looked it up and it sounds like a clogged milk duct but it says that's usually in women breast feeding. Has anyone heard of that at 7 weeks pregnant?? 
Thanks!
