I have been on birth control for about 6 months. In this last months cycle, I did not bleed while taking my filler pills, but did proceed to bleed for about two days on my normal pills. About a week later I had unprotected sex. Then, about 2 weeks later I started bleeding and bleed for about a week (half way through that months cycle of pills). I am about to start my filler pills again in a couple of days. Should I continue to take my filler pills and see if I bleed more during my "period time" or should I continue on to my next cycle of pills? Also, could this be a sign of pregnancy?
