Any help or advice please ladies? :(

So I’m 4-5 days late for my period, I have light cramps that feel differently to period cramping. My nipples and areoles are darker. Slight nausea and very very tired. Still getting bfn?! What’s the latest you can get a positive? I’m never late for my period, last time I was late I was pregnant with my daughter. I really believe I’m pregnant, its just we have no positives yet:(
