ok so I posted a thread here about a week ago because I was spotting a lot. At the 5 week sono my dr saw the pregnancy but no hb yet and a spot where he said he saw a bleed. I had my 6 week sono yesterday and we have a heartbeat that looks great (whew) however he still sees the bleed although it shrunk a little. He also said that I need to come back next week because he's concerned that it may be a twin pregnancy that's not growing quite right. He said he thinks he saw some movement there but he couldn't be sure because its still so small. This morning when I went to the bathroom I noticed 2 chunks/clots in the bottom of the toilet. They were coffee bean size and shape, mostly brown with a little red. I just spotted more brown blood and anther much smaller chunk. Has anyone experienced this? Could I be passing the other "potential pregnancy"? I'm not bleeding any red just spotting brown. Any thoughts?
