2 days late and bfn.. 💔

According to glow, I am 2 days late. I have PCOS and have irregular periods but the past 3 days I've been having cramps like AF is coming. I've had all sorts of symptoms as well. Sore nipples was never a sign of AF coming but for some reasons I've had them the past 3 days. I've also noticed I've been like a ticking bomb. Everything frustrates me or makes me upset. I've had nausea for small things. I don't know what is going on with my body.. so far I've gotten a BFN. 😞
