"I switched from Femcon Fe to Loestrin 24Fe about 3 months ago. The first month I had lose stools for at least 3 weeks. I finally got over that issue and thought that was the worst of my problems. However, the second month I began to have issues wearing my contacts. My eyes would get bloodshot, but not really hurt. I didn&#039;t think anything of it, I just thought I was wearing them too much.  However, things have gotten progressively worse and now if I wear my contacts for more than 2-3 hours my eyes become sensitive to light, and even after I take them out I feel like I have build up on my eyes when I close them.  I am in the process of going back to Femcon, since I never had any of these problem with it.  Good luck!"
