I have a three month long period with no days where I don't have any. I am underweight with a BMI of 14. I am nervous about my blood count because when I took a test on my 2nd month, my red blood cell count has reached 4.20 

I have also experienced vaginal pain every month, there was a time whereas it was so painful that I wasn't able to stand it and I fainted. 

P.S I am 19 years old and I am a virgin
