Have you figured out why you cave that far in? That seems to be sufficient time to adapt to low carbing and not have any cravings. Everyone is different though. Were you getting enough fat or enough food in general? Is it timing? That is, is it due to hormone changes in your cycle? I know that I have a very hard time resisting carbs during ovulation. I crave during the PMS period, too. So, it was/is very easy for me to slip up during those times. Then once I've splurged, sometimes I think "what the heck, I'm out of ketosis now anyway, a few more carbs won't hurt."

I just really wanted to say hello and welcome!
