Without dates of when she got her period, it's hard to determine the probable father. You said you did have sex with her after her period in October and you didn't see her from Oct 9th to Nov 5th, but today is Nov 29th. If she had a period before Oct 9th, and she didn't have a period in early November, it is likely your child. If she had a period in early November, it could be the other man's child. Only a paternity test will tell indefinitely. Some women continue to have periods, even when pregnant.
Hi,
Ok, trying to sort this out in my head and on paper.... Question: Did you actually see the 2 negative tests she took?
She had a regular period in October, do you know around what date? It's important to know when she had a period in October. From what you wrote, if you had sex with her in October, on and before her period, then you left on the 9th, then she would have been on her period around the 9th (give or take a few days) in November. You would also need to know what length her cycles are - does she have a period every 28 days, 32, 34, etc? She only had sex with him one time - on Nov 9th, but met him in Oct? There's a lot not adding up here and I can see why you would be confused. Either way I would demand a DNA test to see who is the father of this baby. If you can provide any more info to clarify that would be helpful. Please let us know how this goes for you :)
