I'm very nervous. We have 2 DC's and no plans for any more. DH had his op last year before DC2 was born. It took me a while to relax and trust it had worked. Even after his all clear test. But I'm now sat here 4 days late. I'm never late, apart from pregnancy, only once ever. Just waiting sat with a test until I need a pee. Has anyone ever had this happen or is it very rare?
