So the doctor said that I'm about 7 weeks pregnant and the baby is 9.9mm is this typically the beginning or end of week 7?
It's hard to say if it's the beginning of the week or the end of the week. I think it's best if you're going to be using the ultrasound (which I assume you got) as a determinant as to the time when you can expect to give birth, just assume that when you got it done, it is the middle of that particular week. Does that make sense? Is that why you want to know if it's at the beginning or the end in the first place? Keep us posted!
