i don't think so.. u took an ecp the day after that might be the reason.. emergency contraceptive pills alter your menstrual cycle and might delay it by a week or so.. but if it's more than 7 to 10 days go for a pregnancy test... don't panic and worry coz that would definitely delay it even more... the chances r very less coz u had protected sex and also took the ecp... good luck.
hey there, are your periods regular? If yes, then most likely your estimate of period due date is correct and 2 days before the expected period is too late to get pregnant. And you do mention that you had protected sex, if a condom was used and it did not break, you should be fine.. Using the pull out method is not entirely safe..
The morning after pill does delay the next period, I have seen it delaying it mostly by 5 days for many people...
There are alot of conception and ovulations knowlegdables on here. From what I have read, you ovulate approx 14 days before your period.. Even if your cycle was short, there would a very slim chance that you would get pregnant having sex two days before the start of your period.
I have seen a couple posts from people taking the morning after pill and there cycle being late.
