firstly,I'm sorry for all your losses. I knew I felt different before I miscarried, was really worried that something just wasn't right and kept putting it down to having ttc for so long before falling pregnant and was just being over anxious whereas with my first the pregnancy was a surprise. Also there was a large gap between my first child and ttc for a second and put down the reason I didn't feel right about the pregnancy to just not remembering what it was like first time, but I guess deep down I knew something wasn't right.
