Seroqel symptoms and conditions

I am 22 years old, have been on Yasmin for two months now, it is my first time taking birth control pills except for taking the morning after pill once, and so far, so good-- I think. The only things that really bother me about this pill are my period comes every 3 weeks--every 21 days--instead of once a month like it used to--and what bothers me the most is this disgusting brown discharge that I've been getting lately. I also experience knee pain, but did not think that could be connected to Yasmin until I read the other comments, and I experience some abdominal cramping (minor) but am not sure if this is caused by the Yasmin. I have not gained any weight, which disappoints me because I am too skinny and that is the way I am built naturally. I do sweat more than I used to ever since I started taking Yasmin, and the sweating is probably a side effect. I also cry more easily than I used to and feel less able to control my emotions. However, I am also on Seroqel--a psychiatric/ mood stabalizer medication--just a small amount--but some of these side effects could be from that or from a combination of the Yasmin and Seroquil and perhaps how they react to each other. Does anyone know by any chance any drug interactions between Yasmin and Seroquil? Also, if I were going to get bad side effects from Yasmin like some of you report--hair loss, excess weight gain, acne, etc.--since I've been on it for two months, would I have gotten it by now and does that indicate I'll never get those side effects from it hopefully? Thanks.
