Marisa: My period is late ...

I wanted to take a doubts, a couple of weeks ago my boyfriend and I did anal sex, and about 15 minutes before he had enjoyed his hand ... is there any risk of pregnancy ?? maybe I've slipped something down, but during the act (anal) he did not enjoy anything ... and my mentoring is delayed, is it pregnancy Dr? I am very afraid
Expert answer:

If no vaginal penetration is difficult to occur a pregnancy, if vaginal penetration can run a pregnancy, chances are low, but there is. Wait 15 days late to do some examination, before 15 days we doctors do not consider as menstrual delay.
