Am I pregnant?

So I was supposed to be my period today, but my period tracker is telling me it’s already a day late. I’ve been on the pill for almost 4 months and never missed a day but have taken it 2-5 hours later than I was meant to on a few occasions. My bf AMD I have unprotected sex but he always pulls out. I know it’s early to say if I’m pregnant or not but I’ve been stressing about it a lot. Ive been nauseous but no throwing up and tired. I’ve had these weird cramps as if I’m going to get my period but then I don’t. I just need my mind at ease and so does my bf. Please help:/
