I'm out too! Is the Prometrium working?

AF came on Saturday, yes while I was in NY. I started the Prometrium this past cycle and it was suppose to keep my AF away until I finished the pills. Well, I had just taken my 2nd to last pill for the cycle on Friday night about 2:00am (up late with family friends) and then 15 minutes later I used the bathroom and AF was here. I was so upset. I still had a pill to take on Saturday night. Does this mean the Prometrium didn't work completely? I've been having a 9 day LP and I was taking the pill at around midnight everynight. So AF came at 2:00am on Saturday (11/28) morning. Does this mean I had an 11 day LP or an 12 day LP? I'm not sure if AF coming so close to midnight means it's shorter or not? I'm pretty sure I "O" on 11/15 making 11/16 - 1 DPO. Thanks!

Sorry to hear that. I think that getting AF at 2:30am would count for the next day so I think that you had a 12 day LP. 12 days is fine, you can definitely get pregnant with a 12 day LP, or even an 11 day LP. My LP has never been longer than 11 days and I have a son. It is really only cause for concern if it is under 10 days, so it sounds to me like the medicine you are taking worked.
