Could I be???

Hello everyone!

On January 16, 2021 my boyfriend and I had unprotected sex and I am not on birth control, dumb of me, I know but he did not ejaculate inside me, he did the pull out method. But the next morning I took the morning after pill. Anyway, recently, a month later - I have not received my period yet but figured it was delayed due to stress and since I have irregular periods anyway because I have polycystic ovarian syndrome. I was suppose to get my period the first week of February but now it’s February 20. Anyway, I have been having light cramping and some small nausea at night AFTER A WHOLE MONTH.

Maybe by period is coming in or is there a chance I might be pregnant?

I’m hoping I’m not but idk. I’m scared to take a test - any advice?
