11weeks pregnancy bleeding usg shows all fine but why i bleed early morning when getting up from bed.

Postplacent bleeding: You may have a small bleed behind the placenta where it attaches to the uterine wall. It's fairly common and in most cases doesn't represent anything serious. It will eventually stop. However, you will need to make sure your obgyn is on the same page as he knows more of the story, so don't just take my advice as final authority.
