UC savings went over £6000 threshold for 2 months but back under before end of assessment period

[Blossomingx]

Hello,
I'm a first time poster, and autistic. (Mentioning as it may help you understand my anxiety and struggles) I was unaware until a few days back that savings over £6000 would necessitate declaring this in my journal which would result in £4.35 for every £250 being deducted.
do I still need to inform them that I went over the threshold when they paid me; although since paying bills etc the amount of savings has gone below £6000?

this happened in September and again this month. Please be kind - I know I ought to have known this rule beforehand but I genuinely did not know. Also bills and groceries genuinely did take me back below the threshold. I’m worried that if I declare this now they may sanction me for not mentioning it although as I said by the end of the assessment period for August and September I was again below £6000

my question is (1) do I need to declare this now? My assessment period ends on 26 October and I’m below £6000 and won’t be going above it, until they pay me. Maybe. Unless something comes up in that time which I need to pay for which means even when they pay me at the end of October I will still be below threshold.
(2) was I supposed to be paid less for these two months, meaning will I be sanctioned?

sorry if this sounds convoluted.
please help I’m worried 😟

There are rules about when income becomes capital:

When income becomes capital
H1050 Income becomes capital if it has not been spent by the end of the assessment period after the one in which it was received.

Was any of the money spent on repayments for loans or credit cards or similar? Payments made on loans or cards are not typically counted as "capital" in the sense of savings and investments; instead, they are payments to reduce a liability.

Also money spent in this way to reduce the balance is not counted as deprivation of assets,

You report your savings on the last day of your assessment period. This is the amount of money in your savings minus any money received during your assessment period.

Example, X has £6100 on the last day of their AP. they received £1000 during their AP so they would deduct that and the savings would be declared as £5100.
