abnormal uterine bleeding
"I was put on Loestrin 24 because of abnormal periods after having my daughters. I did not experience any changes in mood (which is a first for me on birth control). My cup size increased during the first month and has stayed that size. The only negative side effect is that I developed  are two dark spots (Melasma) above my upper lip, which is worsened by exposure to sun. As long as I use sun block, it is not getting worse but it does make me self conscience. Other than that, the pills is regulating me and effective birth control."
