I ve been on the birth control pill Sprintec for nine months. The past two months I ve had spotting right in the middle of taking my active pills, but only a tiny bit and usually only once. I ve been getting my period as normal. Now, this month, I ve been spotting a bit of sticky brown (so I assume old blood) discharge for three days (days 17-19 of my active pills). Should I be concerned? I m due to start my week of placebo pills on Sunday. This spotting is a real nuisance, and I m a little worried since I didn t spot the first six months on the birth control pill, so what gives?
