4 days late HELP!!

Hi :/ my name is Amyy I’ve been late for 4 days I came to visit my husband in Dominican Republic, I am obviously sexually active i have now been here for 1 month how ever I usually get my period on the 8th or 12th of each month... I’m usually pretty regular, I think I’m pregnant. My boobs do feel a little bit soar and I feel tired n sleepy almost the whole day :(
