I am sorry to read your last update. I went through almost the exact same thing. I was 11 weeks pregnant with all the symptoms (including throwing up) and got diagnosed with blighted ovum. I had a D & C scheduled for the following week. Besides having to spend the day at the hospital waiting the procedure is very quick. I got an IV fell asleep and 15 minutes later I was awake. No pain. Had some cramping for a few days that was managed with advil. I went back to work the next day. I had some bleeding for a few days afterwards. I got my period almost exactly 30 days later and ovulated that month. I wanted to D & C because it looked like it wasn't going to happen naturally (although I know it would have eventually). I just wanted everything out of me and to move forward. Like you said, having pregnancy symptoms without a pregnancy is just cruel.
Let me know if you have any other questions. Again, I am sooo sorry for your loss.
