Brown discharge

UPDATE: went to the er because obgyn had no openings that day. They first did an ultrasound, then were going to take blood and do a pelvic exam. Ultrasound showed baby was 8 weeks 3 days, i was supposed to be 11 weeks 5 days. No heartbeat. Next morning i had a d&c.; 😞 either a missed miscarriage or i was starting to miscarry. Unsure of when the baby passed.

Pleaseeee i need somebody to talk to. I have been sick, doctor started me on a zpack. Yesterday i had a very slight amount of pink discharge. Now im having brown discharge and what looks to me like a tiny spec of tissue. Idk whats going on. Is this normal. Is this not normal. I called and left a message for the obgyn. Im scared.
