I suspect your personal loan will be your responsibility if you are in receipt of benefits. Worth calling them straight away, advising them of your impending circumstances and asking about payment holiday - extention of loan period or any other help they can offer you.
If your work is less than 16 hours per week (which I assume it is at 2 days) then you may well also be entitled to Income Support, housing benefit and council tax benefit but as has been said, entitledto website will give you all the details.
And take up free school meals!
All the best with it, scary but doable. x
