"this is my first time being on birth control and i&#039;ve started my second pack a few days ago. so far i have no large complaints. my weight has stayed the same or maybe lost a pound or two. i do feel more stressed, have tender breasts, and less energy but nothing too extreme. no spotting but a regular period. i did start my period 2 days earlier than i was to reach the white pills. will keep posted if anything changes."
