It's great to have so many newbies here on the board, I just love it!
As for figuring out how many weeks you are, most go by when you had your last period. So weeks one and two are supposed to be before you ovulated, three and four should be your 2WW period. Since I ovulated almost four weeks after my last AF, I just used my ovulation date in some of the calculators. That way it's a more accurate representation of where I am.
