On my 6 week u/s they found a subchorionic bleed yet i have had no spotting or bleeding just some light cramping. My GP suggested to get plenty of rest as there may be a higher risk of m/c but i am now 10 weeks and so far everything is going fine. I am yet to have another scan to see if the clot has dissolved or gotten bigger but i'm hoping that it will resolve on its own as i have a 2 year old to look after and its getting harder to try and rest. I too have read some pretty scary stuff on the internet about this condition but my advice would be to talk to your doc if you have any concerns. Hope all goes well for you and big
