It's over... Graphic picture I'm sorry

Kate
I started the misoprostol yesterday since my levels were still rising and the sac was growing still.  This was an awful experiance I have barely slept and it's so uncomfortable.  I have two doses left to insert and I believe I just passed The sac.  Although there was no fetus in the sac I was still shaking and stared at it feeling like there was... This is so hard and I am so sorry for the picture but I wanted to know if this is the sac (and even the complete sac)?  I will finish my two other doses to be sure it's all gone.  This is miscarriage #2 and I feel so lost; why does this keep happening?  We've conceived and have a healthy and wonderful 6 year old so why this? Why now?  I'm so depressed.
