Was I safe during sex?

Ma

My husband just woke me up asking for sex- which I wanted but was a little drowsy. He went down on me (he did not blow into my vagina) but I could feel myself tensing in my belly because it feels better that way. I would try to relax because I would freak about baby and eventually just stopped him and we moved on. Then when I was on top I tried not to put too much pressure on baby. I think I’m being paranoid but we were too terrified to have sex during our first pregnancy so this is new to us. Were we safe? Im 12 weeks. Sorry for the TMI details and thanks in advance for the advice!
