Sue, Interesting, that site gives me a due date 1 day earlier than what I predicted based on the O (ie EPU) date. I'd say your best option is to keep in mind that you have that range of dates to work with and just wait for your first scan. Our bub was measuring spot on for what I calculated at our first scan. My clinic never gave me a due date other than verbally at that first scan. FX the m/s is kind to you and you don't get any. If you're going to get it, it's normal for it to kick in around 6wks, but it varies from woman to woman. Mine started before 4wks.

Afm, I'm annoying DH a lot by making him feel where my belly is firm. Lol, I just find it fascinating that my flabby belly has a firm section in the middle now. The indent that usually runs around my waist where the top of my pants sit is suddenly starting to disappear and I just find it amazing. Also, today at acupuncture, I got pin and needles in my right hand and foot, so I'm wondering if that means I'm getting close to the point where I can't lie on my back?
