HELP!! 😭😩

Alexandra

Ladies! I need HELP ASAP! 😭 so little background story last week on a Wednesday night I went out with some friends. I drank so much I blacked out & it seems like I had sexual contact with one of the guys (I know him). 1 day later (Friday afternoon) he calls me & tells me that I need to see him ASAP because he had a plan b for me, so I took it after school. How do I know if the pill worked for me? Also I should’ve stared me menestral cycle today May 17th. Should I wait a little longer or...? PLEASE HELP! πŸ™πŸΌπŸ˜­
