Universal credit question

Can anyone help I'm on uc limited capacity for work not lcwra and I earn a thousand pounds this month due to double pay at Xmas, I rang uc as they cancelled all appointments normally have every three months, will these just start again once earnings drop again??? And are they likely to be every three months again I was of understanding that if u was on lcw u only had to attend jobcentre every three months, I'm worried I've messed things up earning to much any advice please
