Talk to Gynecologist on Irregular Periods

2 months ago doc ask me to take zoladex injection for my pcos . After that in my next cycle she gave me induction ( follitrope injection 75mg for 8 days along with decadrone 4mg for 10 days. I missed my period and having light pink discharge from last 20 days now.. what should I do? My beta hcg is negative . In the month of induction on day 14 my E2 was very low below 5 amd so the LH surge ( maybe its due to zoladex )
