i tried mircette and was always near vomiting on those. i am on levlite now and i go from one pack to the next without missing a pill that way i dont have a period. i had a fibroid tumor and it was recommended that i have a hysterectomy because of the heavy periods that went with it but i wasnt ready for that so i asked about being on the pill so i didnt have a period and she put me on the levlite. i have no problem with them,none at all after five years.
