ohkay so I'm 18 years old and have always been regular with my cycle since I got it when I was 12 but 2 weeks ago I lost my virginity, we didn't use a condom till the end but I was so paranoid of the chances of getting pregnant that I went to go get the morning after pill, I was suppose to get my period 6 days ago but nothing came, I've been stressing over this. Could it be that I'm pregnant or that since I lost my virginity my cycle has changed?
