My period is extremely irregular if I'm not on the pill... extremely irregular meaning it might come every 4 - 5 months or two times in one month. Crazy.
But I started on the pill about 3 years ago and that MOSTLY cleared it up, but I still have weirdness every now and then. I'm usually not late, but there have been times that I'll randomly start my period twice in a month. It's usually not as heavy the second time, but it's like you said, Lindsey, it's enough that it's there.
I've never been to a doctor about it, because I talked to my aunt (RN) about it and she said she didn't think it was anything major since my period was already rather strange. That said, since your period has always been normal, it might be a good idea to call a doctor and ask.
My first instinct when I read your post was that it's not really a big deal, though... just an annoyance.
Try not to worry too much.
