Am I pregnant or not

So my story is me and my bf and sexually active and we use protection I don’t take birth controls not a fan of that but my periods are always 2-3 days late I usually get my period around the day 30,33 or 35 but this month has been off my last period was April 2nd and me and my bf did it on April 20th since then I’m late 8 days now and on the 41st day I took a pregnancy test yesterday it came out negative and I took one this morning it came out negative am I pregnant or is it just my hormones and stress????
