Pregnancy - when do I start counting the weeks?
I suspect that I am pregnant. Do I start counting my pregnancy weeks from the first day of my previous cycle (the start of my last period), or from the date of conception, around my previous ovulation date? I seems logic to count from the date of conception, but a doctor once told me that the weeks are counted from week 1 of your previous cycle.

From the first day of your last period.
