Question ??

Nijallah

I had sex on July 4 my period suppose came down that day or no later then the 6 on July 4 my boyfriend came in me thinking everything good because I’m about to get my period so I know I’m not ovulating so now I’m two days late on my period I took a test it said negative do you think it’s possible I can be pregnant now or my period just late because I push it back by having sex? I’m so confused and nervous
