I'm 22 & have been on Loestrin24 for 3 weeks. I have bled for 2 weeks straight, which is the most irritating side effect. I also have shortness of breath, lack of energy, slight mood swings, & ZERO sex drive. I had been off birth control for almost 3 years, so I thought I was starting my period early because my body was reacting to the change. Now, reading that this could last up to 3 months before I "level out", I'm stopping this pill asap! I don't recommend it at all.
