Hey, I have been on the pill ortho tri cyclen lo for 8 months now. I have been sexually active with my boyfriend for quite a while. We used a condom almost all of the time but lately we have been using them less but he never ejaculated in me. A couple hours after I had sex with him, when I wiped myself I noticed a brownish tint so I was assuming it was dirt or something but then it's been getting slightly heavier but nothing like my period, more like after period it's brownish with a little bit of reddish pinkish in it so its like day old blood. It's been going on for a few days now and this is all occurring a week before my period is supposed to start. Is this breakthrough bleeding? Bleeding after sex? Or is there the possibility I could be pregnant? (We are not trying to have a baby!) I take my pill at 8pm everyday. I forgot or was late a few times when I first was starting out but I've gotten better at remembering to take it. I have never had breakthrough bleeding before this and I always have my period every 24 days. I do have pregnancy tests just in case so when is the best time to take it?
