Nausea

Some the past couple days me and my boyfriend would have sex and he first told me he came in me a little bit but pulled out the rest of the way.... the 2days after that he came in me all the way without my consent he said he didn’t mean to but we had sex for 10 months and he has never had this problem before but I was eating dinner tonight ( note he came in me last night) and I wasn’t hungry and had no appetite but I was eating a little bit and mid way through I got a feeling I was going to throw up help I think it’s something else there’s no way this is a pregnancy symptom
