HCG Drop

Brianna • 26. Married. Happy. TTC #1. 1 miscarriage, 3 failed IUIs. Male factor infertility. Starting IVF Summer 2020. Foster mama.
So I followed up with the doctor on Wednesday and she told me that I was miscarrying and that they needed to do blood testing for diagnosis purposes. Seeing those levels drop are so painful but I think helpful in healing. I was holding on hope thinking maybe a miracle and that was hurting me more than just accepting and grieving. 
What do I do now? I'm so lost. Miscarriage at 7 weeks. Tried for 19+ months.
