I had a baby in August of 2009 by c section I had my period the following month... but have not had a period since... In the month of January of 2010 I had unprotected sex about 3 times could I be pregnant again.

If you had un protected sex, then yes.
Are you trying to get pregnant again?

Yes, you definitely can.

I think it's time for you to take a pregnancy test or see your doctor. That's the only way you're going to find out for sure.

Good luck.

Yes you could be.
