2 days late for period then had unprotected sex and next day took morning after pill.. 5 days later from taking pill still no period. Should I be worried

Even if you're period finally comes, you should be worried. You don't seem to have self-control AND it appears you don't want to be pregnant. Your behaviors aren't matching your needs. That would worry me, it should worry you.

Sex was designed to create babies, and you crave sex for that very reason, only your self-control will keep you from getting pregnant. Having sex, having unprotected sex on any date, using condoms, using pills, none of that will STOP you from getting pregnant. Only you can do that.

So, to answer your question, yes, you should be worried. You are jumping into the lake and worrying you might get wet "after" you have jumped. You are SO definitely going to get wet.

At this point, you're just going to have to wait it out to see if your period comes. You could skip it completely this month and still not be pregnant. But next month, based on your behavior, you'll probably be fretting the same issue all over again.

Only you can keep that from being the case.
