I asked this question about a week and a half ago,"Im 16 and have been on birth control for about two months. September first I had unprotected sex and ever since my breasts have been sore and seem to be getting bigger. Lately Ive been very moody as well but Ive also been having break through bleeding. Im due for my period today and I figured the break through bleeding would lead to my period but i dont feel like its coming and I cant tell if my moodiness is due to PMS, Birth Control or possible pregnancy. Are these things caused by my birth control or could I possibly be pregnant???" and since them my breast size has been increasing and Ive become extremely nauses from about 5 in the morning to 12ish(I get up early) I just ended my period but its not enough consolation for my boyfriend. Im on my third 28 day pack and I havent had any side effects until about 3 weeks ago so I need to know for me and my boyfriend,are all these symptoms normal for tri sprintec birth control?

I've take the same thing for over a year and im always nauseas and moody, my boobs have gotten a cup size bigger and it seems like they are still growing but i cant wait to get off the birth control pills. They have changed the way I act. Also, i have unprotected sex(besides pill) every day and still not pregnant.
