Hi, Tony, stop worrying, it sounds like she got pregnant on September 26. The weeks of pregnancy are counted from a woman's first day of her last period, not from the day she might have conceived (which would come two weeks or more after the first day of her last period). From her having a 12-week scan on December 5, that not only suggests her getting pregnant in late September but that she would have had a period after having sex with you.
The info I have is through a friend that told me from info he has seen on social media. She has no way to contact me as I am not on social networks and has not got my number anymore as I changed it when I came back from holiday. I slept with this girl 3 times from early August to when I stated early September. She is in a relationship so the boyfriend obviously thinks it's his and I hope it's his but it's something in the back of my mind that's telling me it could be mine with the date I last slept with her and her scan and due dates. Apparently the scan when posted said 12 week scan not 3 months like I stated but near enough. I would do anything for it to be her boyfriends but would like to know for certain as the dates are close. Thanks for your quick reply.
Hi, what is "what looks like a 3 month scan"? Pregnancy scans are not dated by months but by weeks. Did you see a record of a scan that had a 3 on it?
Here is the main way you can tell whether you might have gotten her pregnant -- has she contacted you about this? If not, she is probably sure you aren't the dad. Usually women do contact the men they think they are the dad. She will have access to much more clear and complete information than you have. She would doubtless have let you know if you were even in the running.
You have three pieces of information, one being a scan that you say is "a 3 month scan" (which is not the way scans are notated), one being a date that "it has been said" is in "late May or early June," and one, the clear message in the fact that she has not contacted you. Unless you are hiding from her, I would guess she hasn't contacted you because there is nothing to reveal to you about the baby's paternity.
So, in short, it doesn't sound like the baby is yours, but if you are on good terms with her by all means don't hesitate to write her a friendly note congratulating her on her pregnancy and wishing her well. If she has something to say to you, this might prompt a response from her.
