I am 41 and had my tubes cut and tied in 88 with my the birth of my last child. I finished my period 12 days ago. 8 days ago I started feeling naseaus and it has not stopped, now the last 3 days I have had dark red/ maroon thick spotting. What is going on? I can't get in a car even if I am driving without being really sick to my stomach. I can't into my Dr until weds. I am worried??
