I've been on Loestrin 24 for about 2 months now and it is horrible! I had breakthrough bleeding within the first 4 days of starting the pill and that brown discharge lasted almost 2 weeks. My period came late and now this second month my period came early. I am having the worst cramps I've ever had in my entire life and I haven't been able to sleep for the past 2 nights. I will NOT be going back on this pill next month.
