Talk to Endocrinologist on Sec Amenorrhea

30y/o female, married since 3 years having 2.5yrs old kid. I am facing hormonal disbalance and not getting my periods. I didnt had my periods while 2yrs breastfeeding and still not had periods after leaving breastfeed. It's been 6 months past to stop breastfeeding. I took primulot 5mg for 10 days n got the periods back but on next month again missed the periods then took primulot 5mg for another 6days n got light periods meanwhile done me uterus scan which is fine, TSH is also in limits but prolactin is high (104ng/ml) which then reduced to 58ng/ml after taking bromocriptine for 10days (half tablet in mon n half in eve). Now for how long should i take bromocription n in what doses?

I have no compalins of blurred vision n headache. No history of irregular menstral cycle or miscarriage. Didnt use any contraceptive method. BMI is also fine.
