I am 20 year old and my gyno put me on Loestrin 24 for ovarian cysts I have. I have been on for 3 weeks now and I think it's great. I will admit the first two weeks I was oddly emotional and little things would make me cry, but now I feel very in control of my emotions, and I think it has actually helped me to be more stable. The symptoms I have experienced so far are nausea if I don't eat it before I take it, a little bit of anger over things that usually wouldn't effect me in such a way, my chest becoming fuller (not a complaint!), and my acne clearing up a lot. I was on Ortho Tri Lo for a couple of months and I was a monster. I also tried the Depo (the shot) and it made me an insane psycho bitch and I do not recommend it to anyone. Every birth control you try is going to effect you differently than someone else, so reading these experiences and what happens to each person does not mean you will have the same experience.
