Possible pregnancy

Ka

I stopped birth control bout a month ago. I was supposed to Ovulate the 8th and had unprotected sex multiple times that week. On the 16th and 17th I had a heavy period/spotting which started as brown bleeding. I tested two days later which turned out negative. I was supposed to have my period on the 26th if that spotting Was not my period, but it never showed. Am I pregnant or was the two days of bleeding my period??
