So five months ago I had a d&c for my miscarriage well now I'm five days late, I started feeling my old prego symptoms two weeks ago. Getting more and more "potent" as time goes on. Nauseous, headaches, slight cramps, tired, hungry but feel sick when I eat, slight bloating here and there. I've taken three tests in a matter of two weeks and all come out negative (clear blue "not pregnant" "pregnant" test) 
Has anyone else experienced this? Could I be too early? 🙏🏼
