Could I be?

I just wanted second opinions on my symptoms! I'm 4-5 days late on my period. I'm not on the pill or anything but we try do use condoms everytime we have sex. I have some bloating, extremely tender breasts/nipples, extreme fatigue and my appetite it different than usual. Also about 4 days before my period was supposed to come I had horrific cramps in my abdomen. So bad that I was in tears and it was some of the worst pain I've ever felt. My mom was wanting me to go to the hospital but I reluctantly said no and eventually it dulled down. I thought it was my period but I had no bleeding at all from that episode. Not sure if that could mean anything but just thought I'd throw it in there! Im 18 and don't know much about pregnancy so I just wanted some second opinions. Thank you ladies❤️
