"i&#039;ve been on lo loestrin for a little over a month now. i&#039;ve experienced slight weight gain (no more than 5 lbs, all of which seemed to end up around my mid-section of course!). no increase in breast size, which i was greatly hoping for. i was previously on ortho tri-cyclen for a month and that was bad. the lower dose of hormones in this pill seems to really be working for me. however, i didn&#039;t even get so much as a slight period last week when i was supposed to have one. i&#039;m one of those women who want a period every month, just to be sure so i&#039;m a bit unhappy with the lack of a period on this birth control. i occasionally experience nausea, fatigue and irritability but nothing that interferes terribly with my life."
