How to deal with Medi-cal and temporary jobs changing my monthly income?

Today I was told by my therapist office I have to sign off on my “annuel financial info” for my Medi-cal insurance. Problem is I jut realized when I applied for medical I was making 1500 a month, 4 months later I got a temp 3 month contract making 5k per month I recently lost that job 4 days ago and now I’m in a 1 month temp job with inconsistent hours so I don’t know how much I’m going to make a month.

I worry if they look into my monthly income for the last 6 months they’re going to ask me to pay back but I’m wondering if I explain to them it was a temp situation jobs that it might be ok? I wanted to ask anyone that might know first before I let the cat out of the bag. I should also mention I never had private insurance this entire time.
