Threatened Abortion

Has anyone had a threatened abortion around 6-7 weeks? I went to the ER with some bleeding, not heavy, no cramping, kinda dark red/brownish in color. I had a pap where they said all they could see was old blood no new, they drew blood and said that my HCG levels were good. At the time I was 6w. I had my first apt on the 11th and they said everything looked great. I have an ultrasound on the 27th. I’m currently 8w and yesterday I had more brown discharge, no cramping, no discomfort, and today there’s nothing but regular CM. Has anyone else had this? I’ve had three miscarriages and my second son was also a threatened abortion at 14w.
