Help me

My husband and i had sex on my period days, he didn’t cum inside . I’m not regular and I’m three days late and usually before my period I get cramps I get really sensitive, like i would cry for anything and headaches. Before this three days I didn’t feel anything, and between yesterday at morning I started feeling cramps , like if my period was coming but no period, I got a headache all my pms , but my period’s not here. Right now I’m cramping like hell.

Need to add that I only have an ovarian due to a problem it was found when my daughter was born via c section, and when I got pregnant the only symptom was my period missing but no cramps no pms nothing
