I slept with a girl I was seeing at the time on January the 6th. Between that time, we fell out and stopped talking. Now, two days ago, February the 3rd, she contacts me telling me she is pregnant with my baby? She said she'd been to have tests and scans and was told she was (at the time) 2 months and 3 weeks pregnant as of last Tuesday. So today that would make her three months pregnant. Surly if I slept with here hardly 1 month ago, the child can not be mine? Someone help me with this please? Would be greatly appreciated.

There isn't much you can do now except wait till the baby is delivered and have a DNA test to prove paternity. There is no sense in arguing with her at this point to prove your point. You will go around in circles.

Sounds unlikely from the scant information provided.

If she is three months pregnant, and you had sex one month ago, there is no way she can be.

But if she missed her first period now, she may be 3 week pregnant, not month, perhaps you misunderstood her.

But all you can do is wait and have a DNA test done with child is born
