My baby is almost 4 months old and I am extremely tired even after taking 2 naps during the day. Furthermore, I am experiencing some headaches. Is it possible that I am pregnant?

Yes, it is possible. Have you taken a pregnancy test?

Yes but it could be other things as well. Iron deficiency, depression, lacking certain vitamins, and just plain being a new mom. Have you taken a test?

Are you breast feeding?

It's always possible to become pregnant if you are having sex; however, the symptoms are so different for every women that one sign of pregnancy can mean a thousand things. The only somewhat consistent sign is a missed period and a positive pregnancy test.
