Hi and welcome to HCM, I am also Dr Madhuri so its a double pleasure answering your question. Now about the spotting, The commonest cause of this is missed abortion or threatened abortion if you are sexually active and not practicing contraception. If this is not the case then other reasons are hormonal imbalances, fibroids and polyps [ non cancerous uterine tumors], cervical erosions [ infections of cervix] and ovarian cysts or tumors producing hormone dysfunction. These are very common issues and are not serious. But it is better to get a gynec examination, ultrasound and hormonal evaluation to determine the cause and get treated accordingly. Hope this was helpful, Have a good day and feel free to ask any more queries that you may have. Dr Madhuri Bagde consultant Ob gynec.
