Sore boobs/sensitive nipples all of a sudden..?

Micah

So obviously I had sore boobs and sensitive nipples starting around 7/8 weeks and it last until about mid to late 2nd trimester... Not sure if its normal to go away or not (FTM), but the sensitivity was gone for me. Well now all of a sudden it's starting again as of about a week ago, I'm 38 weeks today. Is that typical or is anyone else experiencing this?
