My husband likes sex a little on the rougher side...

I'm currently 13 weeks 1 day. Does anyone else have rough sex? We had gentle yet, rough sex last night. 

Here's my concern..Yesterday was the first day that I haven't thrown up in a very long time. I normally wake up nauseous every morning regardless, but I woke up this morning and I have no symptoms. Just makes me a little nervous. I know your hormones even out in second trimester, just wondering if anyone else's nausea/vomiting quit suddenly after hyperemesis? Nervous because of the rough sex, and sudden change in symptoms. We haven't had sex a lot since finding out.
