Baby didn't make it.

After almost 5years of trying.. I finally got pregnant this year.. But at my 7th week.. yesterday, I bled and went to KKH. I had a miscarriage. Apparently the Dr said that my baby should have grown to 10-11 weeks by now. Meaning to say during my previous scan did they see wrongly Coz at first the person scanning couldn't find the heartbeat. But last minute she tried and managed to find a tiny bit. Coz it didn't grow any bigger than 3mm since that day. How do I cope with this loss? Everytime I wake up from my sleep, my heart aches and it feels like a nightmare. I can't bring myself to celebrate Eid Adha today. I just feel crushed.
