"i&#039;ve been on tri-previfem going on my fourth month. i have noticed an increase in breast size, extra water weight, tenderness in breast along with nausea and headaches. it doesn&#039;t seem to be cooperating with my body, but i haven&#039;t gotten pregnant, which is good. i don&#039;t get pimples as much as i used to, and i&#039;m more emotional. this is my first time on birth control, and i am not satisfied with it. i will be going back to my doctor for a change."
