how long would you wait to call dr?

Hiccups

So af is 5 days late. But for 8 days now, I've been experiencing several symptoms. nausea, vomiting, sore breasts, sensative to smells, insane fatigue, have to pee constantly. I was getting slight cramps the day before af was due and for three days beyond that but aside from that, no other signs of af coming. I've taken a hpt every day for the past 8 days and every one is coming up negative.

were trying for our second child and I thought this would be less confusing this time around but I feel like maybe I'm just in my own head and making up symptoms that aren't really there. Everything feels like the first pregnancy but still not getting that bfp to confirm it.

how long should I wait to reach out to the dr about late af with bfn?
