Periods 🔴

My period has been a couple days late this month. I'm sexually active with my boyfriend but always use a condom. We check if there's any holes by putting water in the condom. I just wanted to make sure it wasn't pregnancy since I have an irregular sleeping pattern because I have a new overnight shift job, I've been exercising more and losing a couple pounds and also I've been a lot more caffeine than I was used to. And also is this normal? I'm just not used to the irregular patterns. Thanks guys ❤️
