Need advice, need to vent

Hi everyone! Me and hubby have a wonderful 10 yr old girl, my rainbow baby. We have been trying for years and found out this week i am 6 weeks pregnant. I am very discouraged because i went to the ER 2 from bleeding and nothing can be done, all they say is schedule an appointment with your obgyn. I have an appointment next week but i feel like so helpless and its hard to stay positive when everytime I go to the bathroom it looks like a period. This is my 5th pregnancy. 3 have gotten their wings but I dont think I can handle another one.
