Hmmm

good question... I know my week changes on the thursday- so this thursday i will be 25 weeks.... but for the life of me i cant remember how we worked it out. Its "right" as at the midwife apps, the midwife askes me how far along I am- ie 22 weeks, 3 days, and then my answer is always the same is what his little wheel chart thing says....hmmm must have been worked out from our LMP (our 1st scan and lmp both give same EDD!!!)
