Hi vicki_s,
I can't tell you the answer, but I suggest that you phone HMRC on 0300 200 3500 (or 0300 200 3519 if you have a speech or hearing impairment). You can also visit the Gov.uk website to check your National Insurance contributions record online.
If you are now too ill work, and/or carry on your business, you may be eligible to claim UC, if you have no other income ir very little savings.
I think it would be a good idea to speak to a benefits adviser to understand what benefits you could claim No doubt they will also help with the NI calculations.
I hope this helps.
