I started taking microgynon just 8 days ago after switching from cerazette, I vomited on the second day of taking the pill but long enough after taking it for it to be absorbed into my system, I assumed this was just my body getting used to a change in the medication, but now seven days later I have been sick again. I otherwise feel well, could this be related to the microgynon, and if so should I carry on taking it?
