Scared

Im 6 weeks pregnant today but im bleeding just a bit its brownish blood and a bit reddish the thing is i have a 8 month old baby and yesterdy when i was changing him he fell from the bed the bed is like around 3 feet tall so i rushed him to the hospital to make sure he was ok wich he is didnt even get a bruise or anything but when he fell i got so scared and worried that he would fracture his head or might have a concussion and i dont know if that worriedness might have caused me to start to miscarry i already feel awful guilt because my baby fell now i feel guilt because i might have caused my self to miscarry from all my worry to make things worse my husband is out of state he probably wont be here for 2 more weeks or so i feel so alone
