What else could it be? Just stress?

Let me just start by saying I’ve taken 3 negative pregnancy tests so it’s pretty clear that’s not what’s going on. So I’ve had pretty regular periods for the past year, never straying more than a day or two. I’m now 2 weeks late on my period (negative test this morning), cramps, bloating, crazy back pain, peeing a lot, lots of motion sickness and dizziness and super exhausted.

Now the last time I felt this way I was pregnant, but not this time?

Could it just be stress related? Or maybe started off as stress related and I overthought it into symptoms? Not sure?

I know this isn’t a doctors office but just wondering if anyone has any ideas? Should I just wait it out or should I think about seeing a doctor if this persists? Has anyone felt this way and what did it end up being?
