5 days late. Need suggestions!

Ashleigh

So hubby and I have been TTC. This ovulation cycle I went 7 days of high fertility but never got a peak day before giving up from frustration. Hubby and I did do the deed multiple times that week. Now I am 5 days late but I took a digital pregnancy test on day 2 of being late and it was negative. Any suggestions? Could I be pregnant and the first negative was a fake. Been having cramping feeling and been somewhat nauseated
