I just had sex 3 days ago and we didn't use a condom and even tho he didn't bust in me can I still be pregnant and when can I find out???
You can still become pregnant, but not real likely. In about 10 days the home pregnancy tests will be able to tell you.
If you take the morning after pill TODAY you will further reduce your chance of becoming pregnant. It's called Plan B, and it is available at any pharmacy counter (including Wal-Mart) just by asking for it - but it usually is only SOLD to someone 18 or older (guy or gal). Plan B is 85% effective if taken right away and less so as time goes on. It can have an effect up to 120 hrs after inter course.
Stay Safe and Good Luck!!
