Husband said vagina is purple

Last night I was having terrible belly and Vaginal pains. To the point I was throwing up nothing but bile and water. I told him I was having terrible achy pinching pain in my vagina and asked him to look and he said it's purple, this worried me but I ended up toughing through it and going to bed. Two hours later I was back up. I was having a hard time turning over in bed without my vagina is emmense pain and pressure. I can feel baby move the 4 movements in 1 hour deal so I'm just trying to stay calm. I'm in tub now still trying to soak the pain away. Baby movements have decreased but not enough to cause worry to Dr's. I can feel something is off. I'm so scared. I also have an increase in discharge. No blood show or anything of that sorts. No sex nothing has happened so I'm not sure where to go from here
