I'm 23 years old and I have been on loestrin for a year and I liked it my period lasts 2-3 days the most but I noticed that I would get yeast infections and I had never had one prior to taking these pills so I did some research and found out that it can cause yeast infections and Im not sure if this has happened to anyone else. But my doctor would give me other reasons why I would get them. So needless to say I'm stopping it.
