Am I pregnant help please

On may 24th I got my first depo provera shot. I was supposed to get my period june 23rd... it still has not come yet and it’s July 6th. I’m getting worried I might be pregnant. Every time my I’ve had sex we have used a condom as well as the pull out method. One time we did not use a condom but used the pull out method. Should I be worried about being pregnant?
