I am 20 years old. For the past 2 months I have been having extensive night sweats. I wake up in a pool of sweat and when I wake I always feel like I am freezing cold. My menstrual cycle is normal, I am on birth control, but the menstrual blood is dark red/black and heavy. I have also had constant cramps, enough for me to stay in bed all day. I had an abnormal pap about a year ago. Are all these problems connected or am I mixing apples and oranges?
