birth control
"I switched from Loestrin 24 to this pill because I was having spotting for 3 weeks out of every month.  As soon as I started this pill, the spotting stopped and now I only have my period from the middle to the end of the last week of pills (4 days).  Overall, I have few side effects besides some bloating at the end of the month and a pretty bad headache the first day of my period.  I did gain 5 lbs. within a few months of starting this (on top of 5 lbs. from Loestrin), but a few months ago I started a modest diet/exercise plan and have lost 6 lbs. fairly easily.  Well worth it for pregnancy prevention and regular periods!"
