Hi, I was diagnosed with PCOS three years ago, i took all the prescribed medications and my cycles became regular after an year. Now from last 4-5 months my cycles are confusing me. I get delayed periods (8-10days) and very low bleeding with a very bad back ache. The bleeding is minimal and dark maroon/black in color. Also, the vaginal discharges for all other times are very smelly. I use clean n dry wash, but still the odour is there. Please recommend what do i need to do.
