Promising or not?

I’m 8dpo today and I’m having very very light pink spotting... I had the same two days ago and on 2-3 dpo.... this never happened before 🤷‍♀️ I usually have brown spotting 4 to 1 days before AF but definitely not one week in advance... also my head’s been aching for two days now and my boobs are a bit sore... apart from this I have no other symptoms so I’m not too optimistic... what do you think?
