Vaginalbleeding/discharge/pelvicbackpain

Around Feb 1st I started to notices large jelly like mucus with reddish brown streaks come out of vagina. Then I noticed that my cervical mucus the days following were tinted pinkish brown with lookes like strands of blood. No odor, no itching, no green or yellow discharge. Symptoms have gradually started to worsen the tinted pinkish brown turned into almost black blood clots, subsided and then its just blood like instead of a discharge. I've developed more severe symptoms. have waves of extreme nauseousness, sharp stabbing almost a tingly burn in back, hips,buttocks. Crampy dull pelvic pain with some sharp stand in different spots at random, right now it's localized in my right side, shooting pain legs, and my lower abdomen is distended and definitely have fluid build up that has been increasing. Just started now is a sharp achy stabbing in my vagina up at the top, my cervix. my last oeriod was jan 18, i also had unprotected sex day too while on it. not sure if that could be an impact
