Threaten Miscarriage.

Gu
I am 9 weeks pregnant today and just got put on bed rest yesterday. I went into the ER due to cramping and bleeding (which looked like old blood). I was told I have a small bleed therefore I should lift absolutely anything that is not my wallet. Also, I have a small cyst in my ovar. I am extremely worried and scared to be completely honest.. I was told it could cause me to have a miscarriage. I am expecting baby number two and I'm just wondering if any of you ladies have experienced this aswell?  To add to all of this stress, the father of my children isn't supportive or reliable. My son (who will be 2 this august) is on the go all day and it's impossible for me to just be on bed rest and not tend to his every need..
