Unsure on what to do next

[MayChlo]

I’m currently on day 62 of my cycle, my periods are a bit unpredictable atm. My cycles in the last year have been between 57 to 33 days long (only two being as long as 57 days) most are around the 35 mark (always have been). Over a year ago I had a one off 79 day cycle. I know that my period is late if I’m basing it off the recent history. I’m not trying to conceive.
Advice on when I should maybe take a test?

I'd take a test now, but if you haven't already I'd also recommend going to your doctor and asking for a referral to a gynaecologist if you're not pregnant, just to check whether there's anything behind your cycle being so irregular - I've been having weird periods and it's been due to a fibroid, and there are lots of other things which can affect your cycle which can be quite easily remedied
