back at the doctors tomorrow :(

Heading back to the doctors tomorrow after the ultrasound tech was unable to find a heart beat at 8 weeks... I'm still not sure of the fetus' measurements - she didn't tell me and didn't show me the screen. 
I'm likely 5-6 weeks at the earliest but still super paranoid of what the outcome might be...
Also, my stupid doctor didn't give me the right info for the blood test lab, so they didn't look for progesterone/hcg levels which means I'm going to have to go in a second time.. nor did he ask me to do a pee test.... ugh... is peace of mind too much to ask? 
I've already had one miscarriage and l really want this baby.
