r these Signs???

I've been feeling nauseous For the past couple days along with extream thirst. Today I had heart burn with no warning at all Which is weird and TMI but it was almost enough to be vomit tbh Thank god I was already in the bathroom Close to the toilet.

Now I have a runny nose seems to be be a flue which is normal for me but all the rest is very unusual.

Is any of these a sign of pregnancy?

( I haven't tested yet)
