My last period was either 12th or 13th June, I have regular 26 day cycles. I had a scan done on August 12th which showed that I was 8 weeks and 6 days pregnant 1 or 2 days ahead of what I thought. I'm just wondering when I would have conceived because I slept with my ex on 19th June he used the pull out method and then slept with my new partner on 25th 26th 27th 28th 30th and 1st? Who is more likely to be the father? Please help x
