Help! What is wrong with me?

So it’s down to two days before my period. I’ve been under a lot of stress of being quarantined at my college in an isolation dome for a week now. I just found out one of my roommates corona during this first week of isolation. I had to move once more to a different and very tiny room. Aside from the stresses of that I’ve been having the worst stomach pains at night. It’s like a radiating nausea that wraps around my whole stomach and wakes me up and keeps me up at night. Is this a sign of pregnancy or something else? I’m so scared
