One day period

Me and my fiance (soon to be husband in two days) have been having a LOT of sex in the last two weeks of me visiting him overseas (he’s stationed with the airforce out of the states) I was supposed to have a period this last week, and it only lasted like a day, light spotting, little after sex but nothing like usual. We want a baby.. anyone have experience on this. I’m wondering if I could be pregnant. I figured I would take a pregnancy test as soon as I got back to the states, but since I had a light almost non existent period (didn’t have to use a pad or anything) is it even possible that I could be pregnant? I am getting my hopes up!!
