So I had a miscarriage in February and now finally pregnant again. However, I'm scared because I had 2 other children and both times, I was extremely sick before I even took a test. This time around I'm just a little crampy, back is aching, and I get headaches from time to time. Maybe it's a sign that it won't last. Anyone else have multiple children and majority of the pregnancies be the same, but one was completely different from the rest?
