Pain during sex

I'm in the second trimester...22wk. My husband and I haven't been having much sex because I haven't felt great with nausea and round ligament pain. So we tried last night and it was very painful. It wasn't painful like he was too deep, it was like everything just felt so sensitive that it actually hurt with the slightest touch. And it hurt inside and out. I plan to talk to my midwife at my appointment this week but wanted to see if anyone else experienced this and if it ended up being something other than normal pain. It didn't feel normal...
