TTC Questions

My husband and I are trying to have a baby. We have been trying for a month now (I know not very long). I am on my second day of my missed period. I took a test yesterday and it was negative. However, I had a warm but cool (not painful but almost soothing) feeling in the top of my stomach. Has anyone ever experienced this? I don't wanna get my hopes up about it and it not be it again. Any advice helps.
