Frustration and never ending miscarriage

I am so frustrated. I just went to my doctors this morning and I miscarried the sac/baby but still have a big clot associated with everything! I am so mad....I really wanted to do all this natural and I am frustrated that it has been almost 2 weeks and I still have not miscarried everything! I have to start taking the meds today to attempt to get rid of everything...but if that doesn't work then I will have to go in for a D&C. I am so upset. This has just made everything even worse. I finally felt like I was able to get over everything and move on...then this happens and I have all the same emotions all over again. It is so hard and I just want to sit and cry! I don't understand why it takes so long to miscarry and why it is so difficult to get everything out. It makes the mourning and everything that much harder because the trial keeps continuing on. I know that I will never know why God aloud for this to happen and why it has been such a struggle to actually miscarry, but I am continuing to give it to God and trusting that he still has me in his hands even through everything is such a mess. I am praying that God will help me through this trial!
