WOW..all these negative reviews! I have been on loestrin 24 for over a year or so. I had heavy heavy periods so my gyno prescribed these. Other than the break thru bleeding...I have noticed no side effects. For me the pill has been wonderful. My periods are so lite that sometimes all I need is a panty liner. It has worked wonders for me...and I am in my 40's. I have 2 kids and I would NOT want to feel pregnant and these do NOT make me feel preggo at all. I guess it works for some...it's not for everybody! But my experience is GREAT!!
