spotting 10 days before cycle. advice please

[Jen27]

Hi
The last 4 cycles I have had spotting before AF.
for 1 of those cycles I spotted for 3 days before AF, 2 of the cycles 5 days before af and I started spotting yesterday (6dpo) which is 10 days before AF is due!!

anyone know what the cause could be? do you think I need to go to the doctor?

I came off the pill early october so nearly 8 months ago. I didn't have spotting for the first 3/4 cycles


below is a list of the last 5 cycle lengths (though I hve been off the pill longer, I hadn't recorded cycles before then)
29
