Ultrasound-Heartbeat or no?

I go in one hour to see if my little bean has a heartbeat. There should be one there. My HCG from yesterday was a whopping 159,000. That's awesome! At 7 weeks, I am actually at the high end of the scale for once. Now the bad news, today I feel horrible sick. And not the nausea that caused me to think I had cancer and wasn't pregnant. Only an infertile would be so stupid. Or I guess it's more naive. When you've had more pregnancies than living children, you tend to think of the worst I guess. Bad things happen. All the time. No, I've got a cold, and I'm paranoid that means that my immune system is all out of whack and killing my baby as we speak. But I guess there's nothing I can do. But hope for the best. Hope for that little flicker on the screen. Hope that I won't need surgery next week, because this one's different. I hope!
