TriNessa side effects

I started Trinessa earlier last month and it was my first BCP. I've been on my period ever since i started it so I'm not sure if it is because of the pills. I started the placebo(period) pills and now my cramps are HORRIBLE and my period is even worse. Its been 27 days on my period and I'm STILL going strong!

Has anyone else had this problem or suggestions?

I've been on Ortho-Tricyclen (then switched to generic, TriNessa) for well over 3 years, and I can honestly say that I have had minimal, if any, side effects. My skin is clear, my periods are extremely light with minimal cramping and only last 2-3 days. I have no other side effects to speak of (i.e. nausea, vomiting, depression, etc.) My doctor recently wrote me a scrip for Aviane, because she was concerned about the progestrin in TriNessa, but I don't think I'm going to fill it. On this site alone, I've read 50 against Aviane and only 1 on TriNessa.

Every month about a week before my period, I get severe stomach pain and nausea, vomiting, and constipation. I've ended up in the emergency room every month since I have begun taking this birth control pill.
