I’m stressed

So I was fairly dumb and had unprotected sex a couple of times this month with my boyfriend. He never once ejaculated inside me, but I’m now two days late. Being a couple of days late is common for me, but I’m just scared. The most noticeable symptoms is my tender breast, but this is also common in the leading days to my period. I’ve also been slightly cramping for the past three days, but no period. Since it’s only two days I don’t want to test yet. I’m just scared.. I’m only 17.
