"i barely started taking this birth control 2 weeks ago exactly. the first week i was fine, however in the 2nd week of taking them i got my period, i have been bleeding heavily the entire week. i normally have my period for about 5 days, 3 heavy days and 2 light days, with minimal cramps, however this period has been going on for about 7 days now bleeding heavily the entire time, my breasts are in excruciating pain (my breasts normally hurt before i start my period not during my period). i have been so tired sleeping by 9pm. i have had the worst cramps, dizziness, some headaches, and i haven&#039;t had an appetite. i&#039;m going to finish the birth control for the next 3 months and hope that things get better."
