Can your period come on when you taking birth control pills?

It has been my experience that your cycles will usually be fairly close. I've never had mine vary more than a day off, depending on what I've been doing that day. (the more active, the earlier it may start) .

AnswerMy periods always come on a Tuesday, but a day off isn't a big deal. But it should come the same day or the next. If you exercise or active, it will come faster. AnswerI'm a Sunday starter, and my periods always come on Tuesdays. I've been on Yasmin for about a year now. AnswerI am on Ortho Tri-Cyclen and I am a Sunday starter. My period usually comes on Tuesday or Wednesday, but sometimes even Thursday. AnswerI'm a Yasmin Sunday starter and I always start my period on a Wednesday every month. AnswerIt depends. If you have never really had a regular period then it's normal to still have irregular periods while being on Birth Control. my periods are usually a few days off every time. I've even been known to start 2 weeks early sometimes too so it's all good, I wouldn't worry about it too much.
