4 wks with #2 and still no symptoms

Ashley
Hi ladies!!!
I just found out yesterday (thanks to about 4 hpt) that we're expecting baby #2 and other than implantation cramping and a little more fatigue than normal, I'm not feeling any symptoms. With my sweet little boy I had pretty much everything except the vomiting. Anyone else have this "problem" or feel worried that they're not feeing pregnant?
