Weird symptoms

julie

AF due 3 days ago.

Cramps on and off for past week but no period.

Very emotional been crying for no reason etc etc

BFN today

Breasts were really sore but now not so much

Weird metallic smell down there since yesterday smells like period

Waves of nausea

First time I was pregnant I had cramps without period and didn't test positive for a while after missed period (can't remember exactly how long) that's what makes me think something is going on

What do you guys think
