Spotting 6DPO

Leonie

I had a chemical pregnancy at the very start of August but since then had a normal period 4 weeks after it... I'm next due a period on 27th, which is next Friday... But today have light salmon coloured spotting when I wipe... Ovulation was 13th this month so 6DPO today.. And had unprotected on that day and days before /after... Is this just early period or??? Any advice
