abnormal uterine bleeding
"Can't say I love it but I kind of like it. First the BAD: my first month taking this was the absolute worst. I was beyond exhausted everyday and felt like I could fall asleep at any given moment (thankfully this has subsided). Also I noticed that I have blemishes that show up on my neck and jawline randomly once in a while ever since taking this. They're not terrible but I've never had this before. Finally, taking the pill at the same time everyday can be torture.    
Now the GOOD: I have not had a period or any PMS symptoms since taking this. I also have read that certain birth controls can alter hair and weight for some women but mine stayed the same while on this."
