"great pill! last year, after being on a brand of birth control pill for 20 years with light, predictable and short periods, i began to have breakthrough bleeding, horrible cramping and bleeding. lo loestrin was the third pill my gyn put me on and after a week or so of spotting, light cramping, i haven&#039;t had a period since mid-december. so far so good on this prescription, i&#039;m happy to have tried it."
