How long can psychosis last?

Can psychosis be any time frame? Even if it’s just a couple days? I know it could last months to years even but how short can psychosis be?

I ask because I have delusional disorder and I’ll go through bouts where I’m pretty delusional, constantly knowing someone is following me, police are following me home, deities are in love with me, bugs are in my food, hardly taking care of myself and so on where it’s just so bad. For maybe like 3-4 days. Sometimes it gets so bad I’ll have hallucinations that coincide with my delusions. But then I’ll go a couple months where they arent nearly as bad and can function without checking behind me/checking my food

I just recently got diagnosed and they asked me if I’ve ever been in psychosis before but psychosis from my understanding is like a spectrum. Like some aren’t as severe and can last less time while others can be pretty severe and last a while right? But if I’m experiencing a rush of symptoms for a few days where it is all I can think about 90% of the time then am I in psychosis?

I’m on antipsychotics and got put on them maybe 2.5 weeks ago and haven’t had that bad of symptoms since being on the medication and I wasn’t in the greatest spot right before taking them.
