do you think Im pregnant? *read description*

so my fb & i always fuck raw & he always finished ON me, never IN. Last month I was 4 days behind on my period but I started it as soon as I was supposed to end it. All good.. until this month. I missed my period by 5 days & decided to take an at home pregnancy test. It has been 2 weeks since we last had sex & 1 day after my missed period. I came out negative. But I’m thinking I took the test too early. I always cramp before my period but i haven’t cramped all week. I barely started having sore tits today. I was very emotional last week. I’ll test again in a week just to make sure but what do y’all think?

Friends of mine say maybe it’s the sex that’s changing my cycle. I’ve been having it so much more recently as well as stress, but I’ve never fully missed my period.
