Late period from Stress or pregnant?

So I know stress can delay/skip periods but how likely are you to have pregnancy symptoms when stress is the cause?

I'm about 10 days late at the moment, with bfns.

I've had these symptoms even before realizing my period was late

-light nausea since before my period was due, no vomiting but just general queasiness off and on throughout the day.

-I've slept poorly and woken up in the middle of the night to use the bathroom a few times.

-last two night specifically woke up in the middle of the night with nausea almost to the point of throwing up

-side aches/light pin prick cramps, not at all like those I get before af

-excessive milky/clear discharge since AF was due

I was stressed from moving and job hunting during my last period so it could be that but would stress cause all of those symptoms?

Ugh
