Conception confusion

The due date I've been given is Thursday 17th of December.

I've calculated this and used different conception calculators and the most likely date of conception/ovulation I've come up with is Thursday 26th of March.

I'm just wondering could this mean I conceived BEFORE or AFTER this date. By after I only mean a day after.

I had sex on the 24th (a Tuesday) and then on the 27th (a Friday).

This past Thursday I was exactly 20 weeks according to measurements of the baby. I am now 20 weeks and 2days.

I'm not sure because I've never had a child, but I don't think they can ever be completely sure. I mean they can give you an estimation but it's not certain. Like when the woman doesn't know who the dad is on Jeremy Kyle, she may say she slept with 2 people in one week so they have to wait till the baby is born to know who the dad is, they can't 100% tell her from the dates.
Guessing it was two different people on 24th and 27th? Poster above is right - they can't be certain exactly when you conceived. Only way to be certain of fatherhood will be a DNA test, as you could have conceived on either of those dates.

If I were the betting kind, I'd put my money on the Tuesday sex.
