I am 22 years old, weigh 57kgs, suffering from PCO. My doctor advised me to take meprate tablets for 10 days to regularize my periods. The course of which duly ended on the 1st of August. I started getting spotting from Thursday, 3rd August, and its continuing but no heavy flow until now. I am also taking certain homoeopathic medications for a completely different ailment as well as for my PCO. when will i get a heavy flow? and what are the causes of spotting?
