16 days late!!! Negative pregnancy test...

Hi girls, so i tool Ellaone last month after i had unprotected sex with my bf ( he did non cum inside me but still i took ellaone to prevent pregnancy) the sex happened the next day after my period ended.

So today i am 16 days late. I took pregnancy test 4 days ago, its negative. I dont see any preggy symptoms but i feel bloated, i feel pain on my breasts sometimes, i crave sweets as well other than that i dont vomit, no back pains or anything.

Hope my period will come this month 😩 i am getting paranoid af. Does anyone of you experienced skipping period for a month after taking it?
