Has this happened to anyone?

I went to the ER for abdominal pain and they said it was ovarian cysts and I also had BV. They prescribed medication and I finished it but about 5 days after I had more abdominal pain and pink watery discharge. (It was running down my legs) now the discharge is light brown with red streaks and thick. No sti I was tested. Also I haven't gotten a period since 12Sept and I'm never late. Negative pregnancy tests. Help
