Late, bfn

I am currently 5 days late with no sign of AF coming other than feeling nauseous yesterday. I’ve taken test after test and it comes back negative. My period is usually on time or a couple days early according to Glow.

My question for you is: has any of you gotten a bfn after a late period and then a week or so got a positive? My OB told me to wait another week, take a test & let them know the results either way. I hate waiting! I feel like my body is playing tricks on me. We just want our 2nd baby!!! 😢
