UC working it out

Is anyone good with working out UC? I’m trying to predict if I will get any UC for May. My sons nursery fees will be £828 (payable 1 month ahead) so paying next week. And my predicated salary £1100 (part time) and I will be working overtime will add about £1300 (overtime is higher pay). Just trying to see if it’s worth doing overtime or will I need to pay from my salary the nursery bill 🫣 I’ve posted below my recent UC statement for April to give a rough idea Salary £2500 (after taxes) Nursery fees £828
