Hi, Am On Yasminelle For The First Month, Took It

Hi, am on yasminelle for the first month, took it almost perfectly and am on the placebo week now. I had light bleeding starting day 21st and progressed to a (probably?) a period on day 24th. Now, two days after, I have almost no blood at all but bad abdominal pain, tender nipples, low back pain and feeling of frequent urination. Any advice? thanks.
