To the ladies who are taking this form of bc can you give me your thoughts/experience on it? I've been taking trinessa for 9 months now and i don't think it's working for me. I get really nauseas every time I start a new pack, my periods are still awful, it's given me a lot of anxiety, and I deal with a lot of water retention on week 2 of the pack. Yasmin is lower in estrogen than trinessa (ortho tri cyclen) so I was thinking it would be a good switch since I'm sure its the higher dosage of estrogen that is messing with me. Thoughts on Yasmin??
