Periods late!

Hey! Just looking for some comfort and advice I guess. I’m too anxious to test yet lmao. My cycle usually ranges from 29-40 days, but rarely ever goes over 35 days. Like.. only once has it been all the way to 40. I’m currently on day 37! 4 days late! I know the app is just a guess but I’m worked up over it.

We would be fine with either answer, I just don’t think I’m ready to cope with a potential positive test. My husband really wants to be a dad though! I’m thinking it could just be a change of environment.. did that happen to any of you? The last month I’ve moved out of my childhood home, went on a 2 week vacation, switched jobs, lost friends etc. it’s been a whirlwind for sure. Could this be a cause of a late period? Or am I crazy and need to test asap?

Not experiencing my typical pms symptoms. I usually am super uncomfortable and bloated, no energy or anything. I have an acne breakout so that’s kinda a symptom. Been pooping frequently.

Thoughts??
