Hmm... I don't want to be negative, but I was just doing the math in my head and that didn't seem right (my baby was conceived around April 1st and I am due December 23rd...). So I checked an online due date calculator and it seems that if you are certain about the conception date that the due date should have been a month earlier (weks of pregnancy are counted from the date of the last period, not the conception date. My LMP was March 18, so I am almost 33 week pg). Sometimes women don't ovulate the day of intercourse, so conception could be off by a few days, and occasionally pregnancies do go to 42 weeks, and smoking can indeed cause low birth weight... but that still looks like she would have been 44 weeks at birth if I am seeing this right... and that seems kinda unlikely. I hope for your sake that I am wrong or the dates may be off. We see a lot of men on the forum that ask these questions hoping the baby is NOT theirs, so it is wonderful to see someone who wants it to be positive. Either way, if she is part of your life now, I hope even if the test comes back that she isn't yours biologically, that you can still be part of her life. Everyone deserves as many people who love them around as possible!
Well I conceived on Feb 7th. I was due Nov. 2nd. Had my son at about 38 weeks and was born on Oct 15th.
