I think you go from the date of ER, and add two weeks to get the traditional how far along are you - i.e., if your ER was the 25th, you would be 15 days, + 14 days, = 4 weeks and 1 day today.....
Any thoughts on that any prego ladies?
Well, I have bought one HPT thats digital, so I'm praying for it to say the right thing tomorrow am before I go for my beta at 8am. I'll keep you posted!!
