Im 22 years old a5 have irregular periods. I had unsafe sex with my boyfriend just two days before my period was scheduled. He says that he didn't evacuate inside and now I am late for my period by a week. Is it possible that I am pregnant?
Or maybe it's just stress or my irregular periods??

Maybe just irregular periods, may be stress, and may be pregnancy, sorry no way to tell at this point,

If the sex was just 10 days ago or so, it is too early to test. Best just wait for next month and see if you get that period, if not, test then
