Can I be pregnant?

My period ended on the day of my wedding and went on our honeymoon 2 days after. We made love that week and the week after severally. Then I traveled to the states back home and to work. The following week after my arrival my period came which was early cuz my period is btn 28-32days and last for 5 days. But this one came 26days and lasted 7 days. I’ve been feeling nauseous every day for the past 4 weeks but don’t vomit, fatigue now and then. And also breast has become a little bigger. I’m afraid to do the test at home and it will come out negative. My heart will be broken.
