Have your partner ever called you "bad names"?

I just found out I'm pregnant after 6 months trying, I'm now in my 6 weeks and me and my partner were having an argument over nothing and mostly I was tense and nervous and I've been moody, so I wasn't really nice but I would never swear at him as I respect him very much. Instead he called me b**** that rymes with witch and I was shocked. Have your partner ever called you that?
Now it's been a full day we haven't spoken to each other or even looked at each other.
Don't know what to do..
Feel very bad though, what should I do?
Are you girls experiencing new and frequent fights with your partner since the discovery of the pregnancy?
