I'm a little concerned and need any possible suggestions with regards to my irregular periods. Last month I got very light periods ( no heavy flow and only for 4 days) and this month it seems I got periods 8 days earlier. I just started going to the gym and doing weight training. My weight is about 90+ kgs and I'm 40 years old. Looking forward to possible reasons before I take a proper consultation. Thank you too all you expert doctors.
