Hi. I am 26 yr old female. I have hypothyroidism, I haven't had a menstral cycle in about 6 months. For the past 48 hrs I have been vomiting, cant even keep water on my stomach, I thought I just had a stomach virus/bug, but then this morning I started having a dark brown almost black vaginal discharge. Just looking for some insight on what the problem is and if I should be overyly concerned. (My OBGYN doesent have an opening for 3 more days)
