I had an u/s done last week - was 8w1d when the u/s was done.
I'm sorry you are going through this. My thoughts and prayers are with you and your little one. It sounds like a subchorionic hematoma or hemorrhage to me. I had a small hematoma on the ultrasound I had done at 4 weeks. The doctor just told me to take it easy. He didn't have to tell me pelvic rest since my DH is back in Iraq, but I'm sure he would have. Sometimes these resolve completely on their own by being reabsorbed into the body, sometimes they cause some spotting.
I had one with my last pregnancy.
I had the same thing (subchorionic hematoma) with DD.
DTD = doing the deed.
