Elmersglue, The morning after is a very high dose birth control pill which will make it very likely that you will just bleed in the next weeks from the hormones.
When did you expect your period?
PLEASE be more careful. Emergency birth control pills should not be used as birth control. Its got a quite bad success record compared to other methods. Unless you know your boyfriend's sexual history and the history of his previous partners, you are endangering yourself by allowing him in without a condom. When you get pregnant, you will be the one ending up with the problems, not him.
