With a combination of female health problems, and not wanting anymore children for the time being, I decided start taking birth control pills once again. That was over 7 years ago, and I'm still taking the same pill I started with. Trivora - 28 is a 28 day birth control pill which is taken nightly. The case in which the pills come in is foolproof, so you never get confused. Trivora - 28 also helps regulate your monthly cycle, so you know exactly what day your going to start, and stop your cycle. That might not seem like a big deal, but any women with irregular cycles knows just what a pain they can be. I haven't gained no weight while taking the pill either. Trivora - 28 also helped me with cramps, that was associated with my cycle. The best part of all, Trivora has kept me from getting pregnant. Trivora - 28 cost $25.99 for a month supply at CVS. You must have a Dr's prescription in order to buy Trivora, but it works wonderfully. I highly recommend any women considering birth control pills as an option to keep Trivora in mind. Although there are a few cheaper birth control pills available for less, I would never use anything else.
