Oh Maybe! Try not to stress (although easier said than done!). I can understand how you are feeling

Your "bruise" sounds like what I had at 5w6d with my son. It was called a Subchorionic Haematoma or Haemorrage. Basically when the egg implants into the wall, some blood can come away and form a clot or a "bruise". Either you bleed it out or it is reabsorbed by your body. I only had the one bleed but it was scary as heck.

I have my fingers crossed that everything is fine and settles down - but seeing bubba in there with a healthy heartbeat (and it definately isn't too fast ... mine were always around that speed at that gestation) has to definately be a good sign. Sometimes things you eat can have an effect on bubba's heartrate too.
