Hi so I had my period Sun-Thurs and I had unprotected sex Thurs and Saturday night I took a Plan B later that Saturday night yet five Days later on the upcoming Thursday Night I started to show light dark brown blood like discharge the next day it was blood and was like that until sunday now today Monday it is back to spotting like are these side effects of me taking the plan B? Because I just had my period a week before taking the plan B? Can someone let me know I just want to know why I’m bleeding? Cause I know it can’t be my period if I just had it.
