Pregnancy

I had unprotected sex with my boyfriend around the 24-26 he didn’t pull out 3 times then again around the 3rd I was suppose to get my period the 1st so I’m currently 5 days late ...I’ve had sore breast, sickness, and EXTREME mood swings .... like crying over going to work for 30minutes.... I took a test and it was negative I’m pretty sure it’s because I took it too early.... what’s the chances of me being pregnant? Am I most likely pregnant or could it actually be negative?
