pregnant or not....

Abby

My SO and I had sex the day after I ovulated, i was supposed to start my period yesterday and I haven't I'm now 2 days late. My SO bought me a home pregnancy test and I tested on the 2nd and then again yesterday evening, both of them showed up negative, but my sense of smell is stronger and my taste buds are off anyone experienced this before? Pic of my daughter for attention.
