I’m so scared :(

So I had unprotected sex with my boyfriend exactly a week after my fertile week and he pulled out before he came.. I took a pregnancy test 6 days after having unprotected sex and not coming on my period the day I was supposed to (which was the day I took the test) and got a negative. But I’m now 3 days late. What do you girls think? Pregnant or not? Please help :(
