"i&#039;ve been using microgestin 1/20 now for 2 weeks, i&#039;m going into my 3rd. at first i noticed that my breast were very sore but within the past couple of days i haven&#039;t noticed it as much. i also know that i have one week left of this pack and i&#039;ve already started my period, as well as the cramping.  and i haven&#039;t been as hungry as usual.  i can live with all of these &quot;side effects&quot; as i guess you would call it.  but the one that i haven&#039;t gotten used to which happens to be the worst one for me and that is dizziness.  its not an everyday thing but its happened twice now in 2 weeks, twice in a week. the first time it lasted for most of the day, the second time it was just in the morning.  i have a doctors appointment at the end of this week so we&#039;ll see."
