Talk to Endocrinologist on Medical/gynaecological Condition

I'm really really depressed about something which is the reason I've turned to this platform. Recently, I observed a few changes in my body which are not very pleasant. Firstly, I started to go bald on and around the forehead ( the male pattern baldness), I always always, as long as I can remember, had hairfall issues too but recently it reached an alarming state where the baldness is very apparent. Then I also had irregularity with my periods. Though I'm almost skinny from the waist up, I've stubborn fat around my waist. No matter how much I try it just doesn't go away. I'm pale and anaemic (with an hb of 11, the last time i got it checked). With all these problems when I tried searching on my own I concluded I could either be suffering from hypothyroid or pcos. Under these circumstances, do I need to consult a medical specialist or a gynaecologist ??? TIA.
