When did you take your tests? Could it be that one was taken with FMU and the others not?
As far as PMS and early pregnancy being similar I agree completely. I have been convinced almost every month I was going to get my BFP... This month I haven't had any PMS symptoms yet (I usually start having them a week to a week and half before AF is due) so now I'm thinking "maybe this month I really am since I'm not having symptoms."
This is why I try not to test till at least 15dpo. Most months I don't need to test because AF has shown up by then.
