Hey guys I have a question

So while on a vacation trip with my boyfriend we had unprotected arc twice but he pulled out and other times we start off unprotected then use a condom since I’ve been back and before we left I started getting nauseous after I ate really hot sick to my stomach like I would throw up I can’t even eat the amount I normally do and I’ve been very sleepy and sleeping more than normal..what do y’all think?
