Just lost our rainbow baby

Katie
We lost our first at 16 weeks in March.  Got pregnant again, went in for our first ultrasound a week and a half ago and the baby should have been 7w6d but was measuring 4w3d.  Dr thought our dates could be off and had us back in for a rescan this past Monday - baby had grown from a yolk sac to a yolk sac with a fetal pole and a tiny heartbeat.  Dr said unlikely that the baby would make it - gave us less than 50% chance - but we still had a tiny bit of hope.  Went in for blood work Tuesday. Tuesday night I had a tiny bit of brown spotting - dr office said don't worry about it - normal.  Wednesday morning there was a little more, and by Wednesday afternoon there was red. Dr office said if I started to cramp or bleed through more than a pad an hour to call back.  
Well at about 1am I started getting awful cramps and vomiting - and a lot of blood.  Continued til about 5am when I'm 99% sure I passed the tiny gestational sac.  I called the on. All nurse and she told me to go to the ER but I chose not to - I wasn't bleeding through pads and I knew there was no stopping this.  
Had blood work done again this afternoon and a follow up appt on Monday when the dr said we will discuss meeting with a high risk specialist. 
I am so sad, angry, and disappointed.  I'm one of the less than 1% to lose in 2nd trimester, now again in a tiny minority to have a 2nd miscarriage In a row.  I'm beginning to lose hope of having a baby.  I'm 34.
