if anyone has ever experienced this or know anything, please help. I am currently on the Ortho Tri-cyclen birth control pills, for the past year. My boyfriend and I have unprotected sex (I know, that's bad), but I've always gotten my period on time every month. I usually take my pill at 10:45pm everyday, but I changed it to 11pm two months ago. That changed from starting my period on Friday to Saturday. I am guilty of taking my pill 15-30 minutes later a few times. However, I didn't start it on Saturday this week and it's already Monday. Yesterday, I noticed a little bleeding and didn't know if it was spotting or just the pills giving me a really light period, but I haven't bled since. I usually never experience spotting.
