According to your LMP your date of conception was most likely 1/1/11. Did you see your boyfriend New Years Eve? But if it's possible your cycle could be off get a paternity test after baby is born and that will give you a 100% answer. Good luck!

Ultrasounds for dating purposes are only accurate in the first trimester and so it could be off by up to a couple weeks. Only thing you can do is get a paternity test once the baby is born.
