A 22-year-old female asked:

I am 8wks pregnant and had my last period on 12/1 but a irregular one could i have gotten pregnant after i had sex around 10/19? or conceived way after?

No and Yes: There's no way that this 8 week pregnancy could be from october, because that is 2 months earlier. This pregnancy is from an egg fertilized in mid-december, plus or minus a week. So, yes, this one was conceived "way after".
