Late period

My cycles have become irregular the past 6 months likely due to stress, hormonal imbalance, poor diet, poor sleeping, and my iron deficiency. This past month me and my boyfriend started having sex with a condom and pulling out before he finishes if he finishes. We also always check for any holes in any of the condoms we use in which there have been none. I started a physical job a few weeks ago and also got into a car wreck yesterday and my period seems to be 3 days late than projected. Is there any way I could be pregnant or am I just late because of the crappy way I lead my life 😂
