Having a miscarriage... again

Why can’t my body do what it’s meant to? Im so confused and hurt. Everyone says god has a plan and it happens for a reason, but what is the reason?! Why do I need to have a miscarriage? I don’t understand. I had a healthy pregnancy after my first miscarriage and here I am again experiencing exactly what happened three years ago. I’ll spot for weeks, slowly getting heavier and heavier until I finally lose my baby. It’s devastating. I know this is horrible to say but if I’m miscarrying I just want it over and done with so I can grieve and move on. I don’t want to wait weeks. That gives me false hope. I just want to be normal and be able to have a baby. I can’t take it. I can’t lose another piece of me.
