I had unprotected sex on a Monday I took a birth control on a Wesnday and I want to know would I be pregnet.. or is it to early to tell

What type of birth control pill did you take ? Was it a morning after pill ? Or was it just a birth control bill ( they are not the same)

But if there was no protection, if you were not on any birth control, of course you could be, and it is far to early to test, you have to wait till it is time for your period and see if you miss it or not.
