Feel pregnant but test negative :(

Chenise
Has anyone else felt pregnant but when they go to take a test it comes up negative. I'm having all the sames signs and symptoms as I did when I was pregnant with my first child. I keep having all these dreams where I'm pregnant and what not.. idk.. just feeling bummed that all the tests come up negative. My husband and I are trying for our second baby, I feel as its gonna take forever!!!
