When I became pregnant I knew immediately. I was extremely tired, sick, and my breasts were tender. I contacted an office to get an internal sonogram, and find out just how far along I was. The midwife didn't say much. I had my ultrasound, and she said though she saw the sac, and a little blob she said was the baby, she was worried about its progression and wasn't sure what she was looking at. She guessed the baby was only 5wks.
She did order labs for Hcg because she was unable to see the yolk, and that worried her. So I went to get the labs every other day. The one from the day of the ultrasound was 45,000, two days later it only went up to 49,000, and two days later dropped to 39,000. The midwife called me and said due to the drop it was a miscarriage. She asked if I had any spotting or cramping, and I did not. She seemed a little surprised about this, and said that I should probably start within the week. It's been over a week and nothing, I don't feel pregnant but I'm not sure if that's my emotions giving up completely on the idea of a baby. I'm trying to think of anything but being pregnant because I have given up hope.
I was able to contact the doctor associated with the practice, and she felt that though having your levels drop is an indicator its not necessarily true, I asked If I could have absorbed it and not experienced the spotting or cramping, though she said I would have spotting regardless. I'm due back on Tuesday for another ultrasound, which would put me at a date to see a heart beat.
I'm just nervous, this is my first pregnancy and I was really looking forward to it. In the past week I have started coping with the fact it's a miscarriage. I'm not sure how to take this hope, because I feel its just going to be false hope, and I'm going to have to deal with this news again.

Get the second ultrasound done. If you're not spotting, or cramping, that's a good sign. Trust the doctor. The midwife should not have scared you the way she did based only on what she saw on ultrasound. Ultrasound is a best guess, and can be off 2 weeks either way. It could be that you're not as far along as you thought, or her tests could be wrong (human error is always possible).

Try not to stress, it's not good for you or the baby. I know it's hard not to, been there done that, but keep treating yourself as a pregnant women, take your vitamins, eat healthy, and try not to stress until you know for sure that you should.

Please let me know how it goes. My best wishes to you.

The one thing that we found while having our child was to only listen to your doctor. The Ultrasound Techs and various other people have a "working" knowledge but not professional knowledge. My wife and I had a few huge scares because of what the ultrasound techs and others were telling us but when we actually talked to our OB/GYN we found out that it wasn't a problem.

I would also question the MidWife a little.
