Yeah, but who wants to have a baby to get rid of cramps?? NOT ME!! Weyes....I used to have mine for 9 days (really heavy and CRAMPY) but they put me on the pill and it's much lighter and only lasts about 5 days (even though all my friends get it for 2 or 3)...and I still carmp, but nothing Extra Stength Midol can't take care of....but I agree with perns...I need at least 3 for it to work...usually 4.
