a little help? slightly freaking out!#!!

Okay so my boyfriend refuses to use condoms because he doesn't like "the feeling of them" we've been together for a while now and we've had unprotected sex during ovulation more than once. I'm getting all these weird mood swings, laughing for no reason and crying over everything (even when my pie was frozen in the middle) also I've been so tired all the time, no matter how much sleep I get I just have no energy. I'm constantly wanting to eat all the time and I've been craving vanilla thickshakes and caramel slice.. also I got a urinary tract infection out of nowhere and I'm just wondering if these are signs that I could be pregnant?!
