I take microgynon every day (the pill). I'm aware I should take a break every so often but I hate getting a period, and after checking with my gp, I very rarely take a break from it. So despite taking it every day without a break recently, I just started a really heavy period. Definitely not just spotting. It's lasted three days so far, I'm bleeding through my tampons, having to wear pads as well.

Is this worrying, or is it just likely my body needed to take a period and didn't care that I'm on the pill?

Thanks.
