I'm on Aviane birth control pills and take them at the same time every day (within the hour.. though once I was two hours late). My boyfriend and I always use a condom and have had intercourse once so far this cycle. I'm just finishing the second week of active pills, so my period should be due in a week. Today I started having some light bleeding and cramps and I'm not sure why! A lot of articles online say that it could be implantation bleeding; however, I'm not sure what the likelihood of me being pregnant is, since I'm consistent with my pill taking and we use condoms. I've only been on the pills for 4-5 months, so could this be my body still adjusting? The only other irregular bleeding I've had was when I was at least six hours late taking a pill in past months and my period started early. Could this be from the day last week when I was two hours late? Otherwise I've also heard that stress can cause irregular bleeding. I have been stressed but I don't think it's to the extreme levels causing hormonal changes. Any advice would be appreciated!
