DO YOU COUNT FROM START OF PERIOD OR LAST DAY

DOES ANYONE KNOW FOR SURE?

I went to the doctor today to get an 8 week blood test.
I had been to another doctor on the other side of town when I first found out a month ago.
The southside doctor (First doctor I went to) Counted how far along I was by the last day of my period (A period which only lasted 3 days)

And now the other doctor I went to (Second doctor) Said you count it from the first day of your period???

IM SO CONFUSED....?????

Would it be worth maybe just going for an U/S..?

Ok so the FIRST day of my LAST period was 20th of Oct 2010.. but what my mum and I were wondering was because my last so called period only lasted 3 days and was very light but with the same cramps.. could that not have been my period ?? I'm so confused because 2 different doctors have given me 3 different answers to how many weeks preg i am.

1st based it on the last day so my due date would be 27th of july  and because i went on the 1st day of my missed period she said i was exactly 4 weeks. which would make me 8 weeks this week.

2nd based on the first day and said that would make me 7 weeks and 5 days..

AND 3RD i did a due date calculator and it said i am 5w 5d...?????? WTF!!!

Definitely the first day of your last normal menstrual period. (LNMP or LMP)

When counting your cycle days and pregnancy you count from the FIRST day of your LAST period.
