Negative yes or no pregnancy test

ok so my fiancé and I kid our best on trying this month, we had sex on the 29th,30th,31st,1st,2ed@4th after fetting a positive ovulation test on the 29th,31st,and 3rd and finding out I was fertile from the 28th-1st and chart says that I ovulated on the 3rd but today with is 8 days after my estamided ovulation day I got a negative pregnancy test, the ones that say yea or no with a - or a + 
​Was it to early to test??? And please tell me if you think it is  possible at all, I need cheering up please. Plus I've had mild carps the past 4 days is that a good sign?
