So TMI question.....

I'm pregnant. First time mom. Well a bit ago my SO and I were making love and for the first time my boobs didn't wanna die so I gave him the go ahead to touch them, lol. Well he sucked on them (not to hard) and now they burn. They feel like they are on fire. The tops of my nipples almost look a little blackish bruised. Normal? I'm 8 weeks 5 days. TIA.
