I've been on Loestrin 24Fe, for about a year now. This month, after my period last month (which was normal) my boyfriend and I stopped using condoms. So it's the first week of my cycle. On Sunday, I took the pill at 1 AM Sunday morning. On Monday, I did the same thing. (I had sex twice on Sunday and Monday during the daytime). Then, on Tuesday, I forgot to take it at 1 AM Tuesday morning, and instead I took it at 10:30 AM Tuesday morning. I didn't miss 24 hours, just 9 hours.
