Period?

Alright so my period was due 6 days ago. My boobs have swelled up and I’m getting slight cramps this week. I just had sex last Sunday with a condom. I don’t believe it broke and I’m not on birth control. Last time I had sex before that was the end of June. I’m praying it’s just late because I’ve slept with 2 different guys. Ugh :/ do I just wait it out?? I stopped my birth control in April and I’m not sure if I’m adjusted yet or what.
