Trivora and type of birth control

I started taking Trivora in June, 2008. I had to stop taking it after 2-1/2 weeks because I was extremely hungry, tired and was had gained 5 to 7lbs during the 2.5 weeks (same systems as if you were really pregnant). The only very nice thing about Trivora was that my boobs looked great!!! I am a b-cup and it went up to a full "C". Of'course that was probably due to the weight/water gain. I didn't feel good at all. I have never taken this type of birth control pill. I took it because it was an alternative to the name brand birth control pills that I normally take. I made a bad decision in getting these pill because I was saving money. I am not sexually active but, I wanted my periods to be regulated. Boy... I should have never made the decision to switch my name brand. On another positive note... my period for the month of June was very light, painless and short. However... my period for the month of July... still has not arrived. It feels like I am going to start but, I never do. Keep in mind... I am not sexually active... and I have never, ever missed a period aside from my two children that are 17 and 12 years old. I know that the Trivora pill has caused a side effect that I was not expecting. Since taking the pill I have gained approx. 10lbs in one month. Feeling bloated all the time because my period still has not started is something that no one wants. Yes... I feel depressed, stomach pains, nausea and I have frequents headaches. I would not recommend this pill to anyone. Hopefully my period will start so I can feel normal and not retaining water and have a constant bloating feeling.
