High prolactin and pcod. Stop taking it?

I am a 22 year old girl.I had pcod since a very long time .I took pills for pcod in 2017-2018 then left it and joined gym.During the 2020lockdown,I started taking pcod pills again and stopped it on Feb 2021.Then I started with my cycling and gym for which the period was really good during march and april.But I was having hairfall so my gynaecologist told me to get my hormones tested and go to an endocrinologist.my prolactin was showing 60.The doctor told me to do a PROLACTIN PEG AFTER PRECIPITATION test where prolactin was 110.So he told me to do an MRI but as again it is lockdown here I can't do anything.My family doctor told me prolactin can increase due to pcod as well so I started with registrone cr 10mg,normoz for pcod and cabgolin 0.5 twice a week for prolactin.I was also having breast tenderness a few days back before starting cabgolin.Are headaches,digestion issues,gastric issues side effects of registrone?Can I stop taking it ?I took 5pills of registrone till now.
