Scared and worried!

Brittney
I am 10wks and 6dqys pregnant and I have been spotting/bleeding since 5 wks and 4 days had an ultra sound at 7wks and 4days saw a heartbeat and dr said everything looked great! Still can't help but worry and I called them last week and he said to keep my apt for the 18th bc it is still early but I just don't feel pregnant anymore most days! Anyone else have this? Most of the time it is a brownish color sometimes reddish! Sorry if it's TMI!
