Black scabs on nipples and itchiness when moisturized

Ava
Okay so I'm sorry if this is TMI..but I'm only about 11 weeks and my boobs are HUGE, (which I know is normal), but... I noticed scabs on my nipples and didn't really think anything but "ehh, I just need to keep them moisturized". 
So I put lotion on my nipples, AND TELL ME WHY I FEEL LIKE RIPPING THEM OFF NOW?! MY NIPPLES FEEL WORSE!! They itch SO BAD and I don't want to keep scratching and cause myself MORE scabs. How do I treat this mess?!
