Any ladies help a girl out?!:(

Kirsty

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, also have back pain and awfully bad ache, which is exactly what I had while pregnant with my daughter!
