"so far this is the best birth control i&#039;ve ever taken and i&#039;ve tried a lot! i just finished the first pack and had barely any spotting. actually super light spotting started last sunday. my breast did kind of get fuller though. a little tenderness but not nearly as much as i had predicted. i sometimes feel nauseous but it goes away shortly after. i have noticed i&#039;m a bit more tired but other than that there aren&#039;t really any side effects. i would advise you to take the pill at the exact same time and take it in the evening. this will minimize the side effects. hope this helps."
