hi I am on microgynon 30 and at the end of my first pack. My doctor has advised I take this medication without breaks for 3 months due to heavy periods. The last few days I have had a cold and have not eaten much. I feel very nauseated, dizzy and my stools are yellowish when I wipe. Is this likely to be due to the cold virus or could the medicine be playing a part? Should I ask my Doctor to change my prescription?
