Scared!

I'm scared and anxious. All my pregnancy symptoms seem to disappear as of yesterday. No more breast tenderness, no more cramps, no more frequent runs to the bathroom. I'm devastated! I called in my OB/GYN yesterday and was able to convince them to fit me in today for u/s and a visit with a doctor. I have been trying to listen to my body like never before. I'm laying down and trying to feel any aches or pain and nothing. With my DS I was a ball of cramps until he was here. I'm trying to stay optimistic but I'm so scared that I can't think straight. As usual Dr. Google doesn't provide a definite answer but gives me a lot of food for negative thought. I'm preparing myself for the worst but hoping for the best. I just can't stop thinking why this would be given to us only to be taking away, haven't we been though a lot already?
