i actually tried this a year ago pa. for me, effective siya with my dysmenorrhea. i still have the cramps pero tolerable na siya, no need for pain reliever. and yes, d talaga mabaho pempem mo when you have your period. surprisingly, manipis siya pero very absorbent. nagstop lang ako nito kasi super hirap bumili, order pa online, deposit payment, wait for a couple of days, track shipping whereas pag ordinary napkin, makikita mo lang sa groceries.
