Hey I come off my period and back onto my pill, which is Micronygon 30, about one or two weeks ago and then a couple of days ago I come on my period....again. I have taken my pill regulary and have been on it for almost two years and this period is extremely heavy. I had stomach pains before the period but non whilst on it. I am still taking my pill regulary but have started experiencing light headaches and weakness, especially in my legs and ankles. I would appreciate some advice as I'm quite worried! Thank you x
