Re: Blood spot on ultrasound.
I had one with my first pregnancy and that ended in the two year old that is currently trying to "sit on mommy". I did spot a little for awhile, probably until the end of the first trimester but it wasn't too worrisome to me. In fact, I didn't even know I'd had it until I moved at the beginning of the third trimester and asked for my records to take with me.
