Ah, tested again this morning and still negative. I keep seeing threads online where people say they end up with periods that are 10/15/20 days late and it punctures my balloon! Today I am either 9 or 5 days late - still 5 days later than I've ever been since coming off the pill. I'm registering with a new doctor at the moment so if there's still nothing next week when I go for my registration appointment, I'm going to ask them to do a blood test...
