ohhh, that seems awful, what a terrible day it has been *hugs*

I just had my 12 week ultrasound and blood test today.
It was so cute seeing bub clearly for the first time on the screen!!
They did the 12 week u/s and tested for down syndrome etc, but as you said, a blood test also needs to be done to complete the test.
I went straight over to get the blood test done, and the nurse was great (I am very bad with needles, esp blood tests, but i loved this burse, she laid me down, and i barely felt the needle go in!)

Im not too sure what the blood may be, however, in my pregnancy book, i read that a small spotting of blood isnt always a bad thing. Maybe go to another doctor to get a second opinion. I would even write a note to the medical practice, complaining about this doctor.

I had a similar situation with my first doctor. I walked in, stated that i did a home preg test, and i was there to get her opinion. She looked at me, then said erm, ill take a urine sample,,.. she did another urine test, and said...oh yes, your pregnant.
I sat there for a minute waiting for an idea of what to do next, and she showed me the door, if it wasnt for my friend speaking up, and saying....'well what should she do now?'
I would have had no idea.
I ended up leaving this doc, and booking myself into another more local doc, she has been great, and she did a blood pregnancy test and took me through step by step what needed to be done.

I feel terrible for you, wat a horrid exp[erience, i reccommend going to another doc, or trying to book in to your normal doc, just for that extra reassurance and piece of mind.

best of luck with everything, im sure bub is fine.
