"i used loestrin for about 6 months. i switched from yaz because although yaz promised a shorter period, i actually had it for about 8 days. with loestrin, i only had my period for 2 days - major plus. however, as time went on, i noticed that i would get stomach aches and the main issue was loss of sex drive. it took a while to realize that this was caused by loestrin but just keep in mind that this is a side effect.
