I’ve been having a period for 14 days so far.. the first 4 days were medium flow with a mixture of brown and bloody discharge with clots the next 12 days it was heavy flow to start to medium flow and the past two days it has been light but I’m still cramping and bleeding. I was tested for a miscarriage but it was negative for any hcg and I have severe fatigue but no nausea or severe abdominal pain. Should I go seek immediate medical assistance? Also my period was 14 days late.
