Miscarriage starting possibly

Hayley • 32 years old. MMC 8/5/16 at 13 weeks. My rainbow baby, Milo Wild, was born 8/30/17! 🌈 Chemical 11/2020. Baby girl Due 9/9/2021! 🌈
I have been cramping on and off for a few days and tonight when I wiped there was some brown watery looking discharge. I think my miscarriage is starting. It's been 7 weeks since my baby died. I've only known for 1 week. I just can't believe how long it's taking. From when you started spotting, how long did it take? I'm so scared. I have Tylenol, ibuprofen and a rice pack ready. my husband just went on a toilet paper and Gatorade run. I just have no idea what's to come. I'm so scared of the blood and pain. I need some positive thoughts please.
