Im on marvelon now, however marvelon has 0.030 mg of ethinyl estradiol, and only 0.15 mg of progesteron. This is my fourth month, and I can honestly say I've had neausea ALMOST everyday..I just started my fourth pack and am thinking I am going to stop taking the pills today because I cannot stand the constant feeling of being nauseous, but that's just how my body reacts to it i guess! I went to the doctor a few weeks ago, and he gave me tri-cylenlo to try because it only has 0.020 mg of estrogen and goes up to 0.25 mg of progesteron. I didn't end up taking this pill, because switching pills just like that worried me, no matter what my doctor said. I went home and did some research, and found that pills with more progesteron rather than estrogen, help with side effects like neausea and headaches, however! they can be horrible with side effects like, depression and anxiety, basically affecting you emotionally rather than physically, which the estrogen can do. I decided not to take tri-cylenlo just because I'm prone to depression and anixety, etc; So I stuck with marvelon, hoping my side effects would subside, however they havent! but I personally think that is the way my body is dealing with it, and it doesn't mean it is going to affect you the same way! but before taking a birth control pill you want to look at the type of progesteron that is used in it, because they use a different kind in most pills, and you also want to check the level of estrogen, anything above 0.030 mg I think, is enough to cause nausea. like dianette would probably have me sick everyday, only because it has 0.035 mg of estrogen in it. Also make sure you are careful with the progesteron, because if your getting more than your body needs from the pill alone, it could affect you emotionally. Im upset that marvelon is causing me to feel sick

because my moods have been great these past few months! I dont even know what it feels like to PMS anymore.
Just be careful!
Because once your on a pill, and you go off, it could take a few weeks to a month for your hormonal levels to adjust back to normal.
Most people blow of the fact that putting a pill into your body couldnt cause you any harm, but believe me, it can affect you, and you may have no idea its even your pill. but everyones body is different, just be careful!
