*possible trigger warning* how can you tell if you're pregnant with PCOS?

Hi everyone,

I'm just after some advice as my afs have ben really weird this month as my af was due to arrive on the 1st of November, but I had nothing until about a week or so ago as all I've had is either spotting or really light bleeding, but nothing else.

My afs have never done this before. I was wondering if I should the NHS advice line 111 for advice or not?
