Ultrasound today

i just wanted all of you to know that today i've got an ultrasound scheduled and am a bit worried about it. i've had spotting 3 times in 1 1/2 weeks, and that is a little scary. The second time it happened, (on Monday night) the on-call doctor told me to schedule an ultrasound. The earliest one i could get was today. This is not exactly an emergency ultrasound or anything, but it is a "concerned" one, and is much earlier than they would normally have scheduled one. Then when more bleeding happened yesterday i called the nurse and she said it wasn't so great that i have a negative blood type and am spotting. So she talked to my doctor, who i haven't met yet, and he wants me to come into his other office in a different clinic as soon as my ultrasound is done. i wasn't scheduled to see the dr until March 19.

It's scary because i realized today that i have gotten 2 positive pregnancy tests, and nothing else. Haven't gone to the dr and heard a heartbeat, or even had an exam or anything. So today, when i go to the ultrasound, i'm worried about what i will-or won't-see on the screen. i'm having all these very bad dread feelings.

This is a very obvious statement, but i really hope everything turns out well today.
