"i am 18 and started taking loestrin about a year ago, at first my periods stayed the same and where pretty normal. last month my period was 4 days late and only lasted a day or two, it was extremely light as well. this month i haven&#039;t had one at all. i am a little concered about it, but i have been reading a lot about how it can make your period stop all together. i really like having a period because it reassures me that i&#039;m not pregnant. my breasts have grown two cup sizes and i feel like i am constantly tired but other than that it is amazing!"
