"hey everyone. so i have been taking birth control for the last 8 years for my period. i was having a period every two weeks so i was put on the pill when i was 13. i am 21 years old now. i got put on tri-nessa about two years ago. i don&#039;t remember the name of my birth control before then. but it worked so well for me, cleared my acne, easy periods, no problems....until last week. i got admitted into the hospital on friday for a blood clot in my left lung. i have no family history of clots and i don&#039;t smoke so they ruled it that it was the birth control. i wanted people to know to be careful. because i&#039;m so young to have something like this happen. so please take with caution. it&#039;s a very slim chance but it happened to me."
