Bloodwork and bleeding

Crazy day today.

Had my first ultrasound and saw the gestational sac. HCG was 7,786 and progesterone was 31.

Later, at work, I started to bleed.

It's been about 6 hours since the bleeding started, and it has basically almost come to a stop. There is just a very small spot or two now on the TP.

I have decided that it is because of the vaginal ultrasound. I have a big fibroid, and the tech really had to dig for quite a long time around to see the gestational sac. At first I didn't think that could be it because I've had so many vaginal ultrasounds in the past and never had a problem. However, I've done a lot of research about how the cervix engorges with blood during pregnancy, making it easier for a crazy woman with a wand to make a overly-worried pregnant girl bleed.

I hope I'm right, and that the bleeding doesn't come back. :(

Please stick around, baby.
