"i have been on this birth control for almost 4 weeks and i have experienced some side effects such as weight gain. i noticed that my breasts are very tender but they have gotten bigger. my hair does grow back faster also. i shave my arms so after one day i would feel stubble. before i was on the pill i would have at least 3 days before i would feel stubble. i took the pill to get my period regulated but i haven&#039;t got my period this month. my doctor said sometimes you wont get your period for at least six months if you are on the pill. i have also had some mood swings but not severe."
