I had sex with my boyfriend on 29th September, 2018 using protection and then I had ipill. In the month of September I got my periods on 17th or 18th. And before that I got my periods on 21st or 22nd August. Then since 8th October I am having vaginal blood discharge which I though to be my periods. And it continued but the flow was not as it used to be. It is still continuing like I still have spotting. But in between on the 8th 9th and 10th day there was only spotting but again on the 11th day there was blood discharge somewhat similar to my periods. Is this happening because of the pills? And is there any other issue? Or like pregnancy or something?
