So after years and years of me going to the doctors about my excruciatingly painful and irregular periods and me trying all different kinds of pills they've agreed to refer me to an OBGYN at the hospital as they suspect I might have PCOS or endometriosis, I'm not sure what to expect though? I've never even been for a smear test before? Will they want to do an examination? What if I'm on my period at the time? Will I have to cancel? Any advice?
