Thanks everyone for your reply posts and the extra information. I am having another scan today and yes they are internal. After that I see my OB so I'll check with him as to the risk of infection, perhapse once a week is too often to have the scans.

Good luck BAL, each week bub is kicking away is wonderful isn't it! I'll continue to keep off my feet as much as possible, and keep fingers crossed.

thanks again xxxxxx
