Late BFP?

Has anyone gotten a BFP a week + after AF was due? AF was supposed to start 10/22, on 10/21 and 10/22 I had pink tinted cm that was only noticeable if I checked my cervix. Since then I’ve had no bleeding, only tiredness, cramping, bloating, gas, and lots of cm. Hubby thinks I’m pregnant but it’s frustrating because I’m getting BFN.
