I do not want to be pregnant i had unsafe sex last nov 3 . he came in inside a little and he continue outside?

Not likely pregnant: If you have had normal periods since november, then it is virtually impossible that you are pregnant. If you have not had a normal period, then that's another story. Pregnancy tests, even over-the-counter ones, are very accurate. Generally, if you conceived more than 14 days ago, the pregnancy test will be positive. Go buy one to be sure!
