Before I got Liletta my periods were 5 days but the last 2 days were basically spotting. On Liletta now my periods have been at least 10 days but still regular. They're very light but still enough so I don't want to have sex while on it. How long did it take for your periods to shorten or go away, or did they even lighten up at all? If you have a different IUD how was it with that one? I only got it put in on August 18 so I'm still in the initial 3 month window
