since I lost my virginity my cycle has changed?

User Profile
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?

Hi,
Welcome to ehealthforum,
There can be slight changes in hormonal pattern after first time intercourse. The emergency contraceptive pills (ECP) work in preventing pregnancy if taken within 48 hours of unprotected intercourse. The withdrawal bleeding that occurs after 5-7 days of taking ECP usually indicates that the pill has been active in preventing pregnancy. This however may not occur if you have taken the ECP close to your period time (as the endometrial lining takes some time to get rebuilt after periods). Wait and watch for your next periods/withdrawal bleeding which can be delayed (due to the high hormonal content of the ECP that causes changes in the hormonal and period pattern). If you intend to remain sexually active, consider visiting your gynecologist to get started on suitable regular birth control measures to be protected (after your periods). Be regular with birth control use as instructed. Avoid having unprotected sexual contact and repeated use of ECP.
Take care.
