"I've been on this pill for almost 5 years now and never experienced any serious side effects. But I just decided to switch now because lately it seems that the pills are losing their effects! There have been at least 3 times in the past year that my period came earlier than it should. This time totally even 1 whole week earlier! I don't really want to switch because I guess my body is now well balanced with these hormones, but my own opinion is that it's losing effect after this long. I don't know...my doctor said trying other combination wouldn't hurt."
