First of all, hello!

I'm new here and have been lurking into other discussions until I was more or less able to figure out how to use this forum better. I recently had a babycenter account but chose to delete it. Anyway... my question is, do you know the week (or day) that you conceived? The last day of my period was December 1st, I'm just wondering the different responses I will get. So I think that I might have conceived the first week of December. Let me know your ecperiences.

And over all, thank you all for not thinking my question was silly. Over at babycenter they would have ripped me a new one.
I'm glad I asked this question, we all have different cycles yet we're all giving birth at or around the same time. Funny how things work.
