Brisa

Today AF is due. I usually get it right when i wake up & still nothing.. im definitely bloating alot more but cant tell if its pregnancy or pms.. just makes it hard since things are sensitive for me now.. starting out with heartburn and nausea last week to nothing now.. bloating, very light cramps? Got a BFN on 10dpo (sunday) im 14dpo when should i test again?
