Endocrinologist or gynecologist

Should I see a reproductive endocrinologist? I have a gynecologist and he ran a hormone test no ultrasound and diagnosis me with pcos and endometriosis.. which is likely I’m concerned about my fertility I’m 20 years old I want to figure out my body so I’m not 30 and still clueless. he put me on birth control for 6 months and he said he would see if I was ovulating or not.. and then give me ovulation Medicine he has a plan but I don’t feel like he’s concerned I want someone I dig deeper.
