Nervous

Can someone fill me in ummmm so right after my last period like about 2 days after it my bf came over I am a virgin and we didn’t have sex but we were rubbing and he tried to put it in but not even the tip would go in so I thought I was preg bc my period came two days late but it came and the cramps were bad as usual and it lasted 4 days ( my usual period length) and it was regular heavy and everything. But I have a cold now and I feel like I been feeling like gurgles in my stomach like when your stomach makes the rumbling noise and yesterday during work late at night I was kind of nauseous idk maybe I’m overreacting I’m the worst hypochondriac ever I feel like a doctor needs to live with me .
