Pregnacy maybe?


So my period 7 days late, I have taken 3 pregnancy tests all negative, yet I having some symptoms, I'm so confused.been having some crapping lately, exercise hunger, wired dream, achy boobs and such. Has this happened to any of you guys? I have been fairly regular over the last year, this the first time my periods been late and we have been having unprotected sex. So there is certainly a possibility.
