I am 5 days late for my period. I had sex 5 days after ovulation. It was really rough and my stomach hurt for 2 days afterward. I have had period symptoms: bad bloating, really sore breasts, minor cramps (usually really bad) and mood swings. I had an episode 2 days before I should've started and have had relationship issues (I know stress can delay a period) Do you think I am at high risk of pregnancy?

Yes

Period most likely late due to stress. Also if rough sex hurts so much, don't do it.

But at risk, you had sex so yes you are at risk
