Please help a sister

My period is suppose to start tomorrow but I have been having these under belly pains and having passing soft stools

And my breasts are heavy and painful nipples

I had unsafe sex but I took pill immediately I woke up the next day

Please help a sister

Zoom and check

Am I overreacting

Will I get to see it tomorrow

And funny enough I broke up with the guy on 1st of this month

Please help me out
