I have pcos&got put on birthcontrol i wasnt on for 2 months now that im on i've been on for a week is that normal/ok? will all my periods be like this?

I'm not sure: I understand your question. Do you mean that you didn't have a period for two months and now you're having a period for a week? If that's what you meant, it is probably totally normal response to bcp. Give it several more months and discuss w/your doctor. Also ask about other potential therapies such as metformin, which can treat the basic problem of Insulin resistance, and try to lose weight.
