How long does miscarriage grief last?

Caitlin

Found out I lost my pregnancy at 10 weeks LMP, though two weeks prior at 8 weeks LMP my baby was measuring 6+2 and we saw it and the heart flicker. It's been 2 wks since D&C. I've cried 80% of the time since. NYE, forget it. After a ton of wine, I was balling!! Almost told Facebook 1) I was expecting and 2) I miscarried but did it in a subtle way and deleted it the next morning. Just sitting on my couch, husband asleep, 2 dogs cuddled next to me... something stupid made me start crying about it. When does this go away? When can I stop being or looking sad?
