What Causes Vaginal Spotting, Pubic Area Cyanosis And Thigh Bruising?

three weeks ago I was transported to hospital by ambulance. I was in respiratory distress and was intubated. I was taken to emergency room and admitted. I was not aware of anything from the time I was transported to the time I reached the hospital. I was given at least to injections of lovenox while in the hospital along with my plavix and aspiring. About a week and a half later I have some vaginal spotting. I am several years past menopause. I took a mirror to see if I could see anything that might be causing this. To my surprise I was black and blue and purple from the top of my pubic area to my rectum. The inside of my tighs were also bruised. I am wonderings if I could have had some type of injury from being moved or by having equipment from the ambulance between my legs.
