I missed 3 pills of my birth control and it's not the first time I've done that. Last time was in the summer and I just started bleeding for 13 days. This time I missed the pills right before I was to start my period and this lasted 14 days, now 3 days after that I'm not on my period but I'm spotting, im really confused as to what's going on now... When will it stop? Is something wrong?
