There's no way to know whether or not you're pregnant before you take a pregnancy test. There is a possibility that you're pregnant, just as there is always a possibility for women who are sexually active to be pregnant. Instead of worrying about it, because you could be worrying about it for nothing, take a pregnancy test.

You can do this in two ways:

1) Go to your local drug store and purchase a pregnancy test, and/or
2) Visit your doctor or a clinic and ask to have a pregnancy test done

Personally? I would recommend that you do both - get a test from your local drug store and go see a doctor or visit a clinic. When you buy a pregnancy test at a drug store, the results aren't always completely accurate - especially with the less expensive tests. Plus, you may receive inaccurate results because you may do something wrong while taking the test. The absolute best thing to do is visit a doctor or go to a clinic. If you do this, you will get the most accurate results.

Good luck.
