Chrystal- Im so sorry for your loss hun, and i know how hard it is too. I had a missed mc last year and when pg with Izzy at 6 weeks I had some dark spotting for 3 days that terrified me too. I went to my gp - and he referred me for an ultrasound and all was fine. I agree with Carmen - hard as it is, try to relax, keep your feet up and see your dr asap.
Huge sticky vibes to you - good luck.
