This is the first birth control I have ever been on. I wanted the low dose combination pill to lower the risk of blood clots and other things. When I first started I really had no bad side effects at all. My period is way lighter than it was being off of the pill and it lasts only a few days. Sometimes I bleed a little more sometimes a little less or barely at all some months. My breasts have definitely gotten larger but I had smaller breasts to begin with so I don't mind the growth. I have a history of migraines but they were more frequent off of birth control and the only time I get migraines now is during the placebo week mainly. The one thing about the pill that has not been good is the weight gain. I am certain it is from the pill even though doctors tell you the combo pill cant make you gain weight. Before the pill I was 129 pounds and for the first couple of months I didn't notice any weight gain. Until about halfway through about 6 months in, I weighed around 144 pounds. Now I am a year in and the weight keeps going up and I am now about 167 pounds and my BMI is in the overweight category. I am so self conscious and depressed about my weight gain. I don't know if the weight gain will ever stop. I don't want to change pills because this works well for me otherwise but if you get on this pill, please be aware it may cause a ton of weight changes.
