I'm currently on camila, which is a progesterone only pill that you take continuously without placebo. I had bleeding for the first week and a half I was on it, but since then I have not had spotting. However, I did have my GYN tell me that the spotting becomes a problem for a lot of people. He basically asked me when I was considering having kids (I've never been pregnant) and when I answered "about two years," he said "That may hold you over to that time"...So I am hoping it works. I was switched over because they think I developed migraines with aura (awaiting neurologist visit in early January) and people with that who receive estrogen are at higher risk of stroke. Overall, I don't really care for camila, but it's not for GI reasons - I'm having horrible acne right now (I initially went on birth control for acne problems, not as contraception) and I don't like that it's slightly less effective than combined birth control pills. If there was another progesterone only birth control form I could tolerate, I'd love it - They don't like doing IUDs in those who haven't had kids and I don't want to do depo again for the reasons below and also there's often a 6 mo - 1 yr delay in return of fertility and I don't want to risk that. If only they had a nuva ring that was just progesterone!In the past I was on seasonale and seasonique, both of which I enjoyed a lot. For awhile I took them without the placebo weeks, but as my IBS got better, I started taking the placebo and having my period every three months. Back when I was having a major flare in 2005, they put me on depo provera, which also eliminates your periods altogether. It was during that time (along with bentyl and paxil CR) that my symptoms came under control...I'm not sure if one medication was responsible or it was a combination of all three. However, I started having reactions to the shots...A couple days after I got them I developed these horrible hot flashes and feelings of nausea that I could not handle.Of note, I still think that initiating birth control may have triggered my IBS....I had just finished my first month of yasmin when my symptoms began. However, I think not having periods really made a difference for me - If that makes any sense!
