What Causes Shrinking Of The Labia Minora?

Hi, Iam 28 years old with 5.3 height and weigh 47 Kg, my issue is that my labia minora is shrinking and there is a growth of a pubic hair on the hood of my clitoris. I have this proble for last six month. If i go on to the history, on May I had a abortion by taking mefigest and cytolog soon after taking that my labia was swollen, itchy with less bleeding, so my gynea advice me for a abortion after ultrasonoghaphy. During abortion also i had an uneasy feeling in my labia and soon after few days I had itching and shrinking of the labia. I was aksed to do a ultrasound after that but nothing was detected. I was medicated with microbiocidal medicines and infa VT which did not work. this time again I have the same problem. My masterbation is also less.
