metformin does not give you a period, it helps to sensatize your body to the insulin that it makes, which in turn and help in some people for them to have a cycle - but that doesn't mean that if you bleed you have also ovulated
I've been on metformin since 2003, and it never brought on bleeding for me.
I was very use to those one day or even less bleeds, lived with them for a few years before the spotting stopped all together (aka no bleeding what so ever for many years, and nothing could induce it).
