How pregnant am I?

Nicola

Hey, I know this is a pretty pointless question to ask but I'm just curious.

I conceived either on 4th or 6th January. However, my LMP was 28th December. Going by that, it makes me about 4 weeks, 3 days. If I go by the date of conception, then it makes me about 5 weeks, 3 days.

Which is it? Thanks, ladies.
