Kinda nervous

My fiancé and I just moved to another state due to him being in the army the base was having a horrible time getting my birth control prescription transferred over and I ended up having to stop until I got my prescription got in. (In got in two weeks after I stoped) We had sex about 5days after my period ended with no type of contraception. I'm worried that I might be pregnant. So I'm playing the waiting game for my period to come so I know if I can get back on my birth control or to be expecting. I've would have only be off bc for a month.... Any help to put my mind at ease?
