Late and no BFP, is it worth testing again?

Sam

So I am 12 days late I last tested when I was 3 days late and it was clearly negative. I don’t know if it is worth testing again or just keep waiting for AF to come. I’ve not got my hopes up as it has happened before but I have never gone over 14 days late so I’m thinking I’ll test then as that would be later than the latest I’ve been, if that makes sense.

So basically should I Test now? Or wait until I got over 14 days late? X
