@Jem70 : Oh, FFS's!! I'd be frustrated @ pi$$ed off too!! It's hard enough doing this without being given the run around on top of!! Well, if you're down regging with the pill or something and wanted to take a few extra days worth and then stop when you want to, what are they gonna do??
It'd just be a case of "Oh sorry, my AF took ages to come this time when I stopped the pill" It's not unheard of for AF to take a week to arrive once you stop the OCP. No, it's not completely insane at all!! I say go for it if it's just a matter of spinning things out a few more days!!
Good Luck Luv!!
