menstrual disorders
"I'm starting my 2nd month of this birth control, so it's not quite enough time to determine if it's amazing yet or not, however the first month is usually the worst.  I was on Orho Evra for almost a month, when I began experiencing horrible side effects and so my doctor switched me to Loestrin 24 Fe.  The main reason I'm taking it is because I have very heavy periods that last for 7 days, which leads to extreme cramps and nausea as well as feeling faint.  
The first month taking this went extremely well.  I didn't have any spotting, my period started as soon as I took the brown pills and ended once I took the white pill again.  Side Effects: headache, nausea, moodyness, bloating, diarrhea."
