Chemical pregnancy :(

So I think I had a chemical pregnancy. We have been trying for 9 months, and I was so sure this time was it. My period was five days late, my breasts were tender when they're usually not, i had these strange burning cramps instead of normal AF cramps, and I have never been so exhausted before. Well here AF came, five days late. The worst cramps ever. I'm nauseous, I'm dizzy. And I'm heart broken.
