My period is 2 days late

Well I went out the country to visit my soon to be husband on December 14 2017 through December 19th. I had my period from December 7-13. Based of the calendar my peak ovulation days are between December 17-21. Could I be pregnant? I told him about this he said let’s wait for a few more before we can take a test. I said okayyyyy. We are not looking to get pregnant right now so let see. Me with the love of my life.
