Weird long cycle

Hey. So the glow app has been great for tracking my cycles for the past few months. My average is 33 days long, longest prior was 34 days. This past cycle (started AF today boo) was 39 days long. Does this seem normal? Cycles were really consistent since March. And this month we thought BFP since I'm like a week late, but obviously not. Just fishing for someone else who has a similar cycle, I know stress etc can cause a delayed period. Anyone have a long cycle, then get pregnant the next month? I'm super concerned now, thinking I ovulated later than I thought and messed things up. Thanks.
