help me please

Okay I've posted about my doctor telling me at my appointment yesterday that my baby has been trying to miscarry since before my last appointment and my muscles are cramping often and squishing my uterus into a banana shape trying to get the baby out. He hasn't put me on medicine and said he will at my next appointment of he doesn't see much growth. I've had total loss of symptoms besides the cramps. No more sore breasts, never had vomiting, no more hormonal acne... Nothing. Today I'm cramping bad, had headache, and loose stool. My underwear had a brownish/pink tinged discharge completely covering it but it's not super wet. Could I be about to miscarry?
