Hi.. I Had Sex With My Boyfriend Of Course And

Hi.. I had sex with my boyfriend of course and we aren't sure if he was out in time. I ovulated 2 days after we had sex but my period hasn't came yet and that was about 2 weeks ago. My period is irregular due to track but I'm worried. I've been running a fever off and on but I have no other pregnancy symptoms. Can you please help me? I'm really worried
