Miscarriage at five weeks

I am sad to report this, but I just lost my baby at five weeks. I noticed spotting and went to the ER. My hormone levels were 137, which was low for being at five weeks. They did an ultrasound and then sent me home. My now ex-boyfriend blames it on me allowing stress from my family to make me lose our child. I'm still living in the apartment with him. He doesn't want anything to do with me, which I can understand. He is truly upset and disappointed. Tuesday will be his 39th birthday and this baby was his gift. He doesn't want to see me crying or upset. I want us back together but I don't see how now.
