In brief: The latter

Based on a last menstrual period of 12/10, your average date of conception would be on or around 12/24.
That would put the pregnancy at 9w and 5d. This doesn't sound like the date of conception as it's off by more than 5 days (it's off 2 wks, actually). If conception was on 1/7, then you would be 7w 5 days, so more likely it was the second encounter that lead to your pregnancy. Hope that helps!
