I did not have my period in Dec, and Jan. In Feb at the end of the month on the 22nd for about a hour it was brown. I'm I pregnant?

Did you have unprotected sex? If so, then you could be pregnant. Take a pregnancy test, they are fairly accurate and then you'll know for sure.

Please don't repost the same question.

Lots of things can cause missed periods... stress, illness, diet, age, etc...

No way at all anyone can positively answer your question. MD's rely on pregnancy tests for a reason. Wish we could tell you a reliable answer, but its impossible.

Time and tests are your course of action.
