S.A.
With my 4th pregnancy (that miscarried) I had some pregnancy symptoms, but they were different than my previous three healthy pregnancies. I had more nausea than I'd had with any of them. The one thing I was thought was strange was that I wasn't going pee every ten minutes like I'd had with the others. I can remember waking up in the mornings and realizing I hadn't gotten up to use the bathroom. That was one of my inklings that something wasn't right.
Just remember that every pregnancy is different, and it might just be too early for you to be feeling symptoms right now.
