I had a relationship after many years with my sons father then he went back to his girlfriend and a month later I started a new one. Then I found out I was pregnant the ob doc said I went over 41wks and my baby was udue on January 31 2008 but she was born jan 23, 2008. I'm am not sure who the father is and I am trying to figure out if I got pregnant in April or may of 2007. Either april9, or the 17th or may 11, can't figure out which month the pediatrician said the baby was 40wks in the tummy. Help

The only sure way to find out would be through a blood test. Good luck!
