Worried. 🤒

I've been feeling nauseous for about 5 days now. I haven't thrown up but every time I feel like I am I just burp. Everything I smell makes me nauseous as well. My face broke out and I have pimples everywhere. I get this feeling off and on during the day. My fertil week just ended and I wonder why it is that I am feeling this way. ANYTHING and EVERY RESPONSE WILL HELP!!  Ps: I had sex the night before I started feeling like this, it was unprotected and only lasted for about 5 minutes. He didn't cum.
