Yes, From what you describe, it is evident that you have hirsutism, which is significant. And with loss of hair over scalp, and enlarged clitoris and menstrual irregularity, it is important to investigate you for the conditions you mention and certain others too. What ever you have mentioned are all possibilities, but cornerstone of diagnosis in Endocrinology is Physical examination and lab assays. So let's not jump into conclusions.
Please consult an endocrinologist for this condition, even before you consult a OBGY. Unless the OBGYN has expertise in Gyno-endocrinology, it will delay the definitive treatment. And do not worry your issue can be addressed successfully after a confirmed diagnosis.
Hope this helps
