he rubbed his penis on my vagina but he didn't insert it. It was the 28th day after starting my previous menstruation but still i didn't get my period.

Hello Anonymous,

Welcome to EmpowHER. Thank you for reaching out to our community with your concern.

Your vagina is inside of your body. If he did not penetrate his penis in your vagina and did not ejaculate semen, there was no risk of becoming pregnant.

Are your periods regular? Other factors, such as stress, changes in weight and an increase in physical exercise, can cause a delay.

If you miss this month, test for pregnancy and call your physician.

Regards,
Maryann
