I just reccently lost my virginity to my boyfriend on Monday night and it just so happens that he used the "pull-out" method. I was not on any birth control, but I have asked him SEVERAL times if he was sure he pulled out and he reassures me yes, if anything there was only precum. Just to be on the safe side I went the next morning and took the morning after pill around 1pm, the doctors there told me that I could take both the pills at the same time as long as I ate something with it.

My period was supposed to start on Tues. and here it is Thrus and I still haven't gotten it. Needless to say I am starting to freak out. Is there anyway that the morning after pill could've delayed my period? or that my anxiety is affecting it?

Also my boyfriend said that a)he pulled out b) he has had surgeries and c) I took the morning after pill so we should be fine.

Why haven't I gotten my period yet? am I pregnant?!

Given the data you provided (had unprotected sexual intercourse, used “pull-out” method, taken morning after pill, missing period for two days), you might have experienced a delayed period due to the use of the morning after pill and to anxiety.

It is well known that morning after pills might alter your menstrual cycle. What would happen depends on the part of the menstrual cycle. If the morning after pill was taken prior to the ovulation it might cause withdrawal bleeding. However, if it was taken after ovulation it might prolong the second part of the menstrual cycle (called luteal phase), thus delaying a menstrual period for a few days.

You might want to visit a gynecologist for a physical examination, hormonal laboratory tests and ultrasound scan in order to check for pregnancy.
