Pregnant??

My boyfriend and I had sex (using a condom) and it may have leaked at the bottom but I don’t think any got inside.... This was 2 days before my period was due (and it usually comes on time). We had sex a few times before that this month but none leaked the other two times.... I’ve taken two separate pregnancy tests a few days apart and both came back negative..... but my period was supposed to come 5 days ago and i’m scared i got pregnant somehow? what should i do? should i be worried??
