Did you get BFN, but still have a missed period, then got your BFP? How many days into your missed period?

I'm currently 5... 5! Days late... No period... No sign of her... I'm trying not to stress about it, or think about it to much. Also trying not to get my hopes up because I've take 3 tests and both have been BFN... Similar stories would be appreciated. Thanks y'all.
