When I feel great, I worry!

Toni • Our Rainbow is due 1-9-16 🌈
Does anyone feel this way? Yesterday I didn't have any nausea or fatigue which are my only real symptoms right now. When my cramping weened down a few days ago, I freaked! And assumed I must be having a miscarriage, as I had one last month. Now I'm worrying that not being sick or exhausted means the same thing. I can't even enjoy having a good day. Do any of you ever feel that way?
