Pregnant?

Hi, my period is around 4 days late (was supposed to come June 12th) and I took a pregnancy test two days ago and it was negative. I had unprotected sex on the 7th of June. Do you think it’s possible I’m pregnant? I have cramps that feel like my period is supposed to come and my boobs are extremely sore to touch and very “full”…

Anybody experience anything like this?

Should I test again in a day?
