Talk to Gynecologist on Irregular/late Periods

I was having irregular periods/late issue for last two years. I visited nearby Gynecologist and she gave me medication which was in plastic bottle with no name on it. Anyhow my periods remain regular while I was taking medication but flow was too light. After 5 months when I left taking medicine my periods were missed again. So I changed my doctor and she advised me to do pelvic ultrasound when I missed my periods. Reports were normal and she gave me medicine for overdue period. She prescribed me progyluton and slix sache. I decided to start seed cycling with walk and exercise reduced 5 kgs weight and periods are regular Alhamdulilah for past 4 months. I'm still doing seed cycling. My period flow is less for day 1 and light spotting for next 2 days. Is it normal? And for how many months seed cycling should be done? TIA
