Still spotting... (C2;CD31:9DPO)

I have been continously spotting since yesterday - sometimes bright new blood, sometimes older brown blood, but it's been there virtually every time I've been to the bathroom. Cramping still continued last night and in parts during today and this evening too.

I am now virtually sure there's no chance of me being pregnant this cycle and am thinking now to the next cycle in gearing myself up for that.

I'm quite puzzled as to why my luteal phase (period between ovulation and menstruation) would be so short... normally it's 14 days - but I'm not even close to that yet.

Anyway, I definitely can't call the spotting I have had as a full bleed to count is as CD1 of C3, so I'll just have to continue the waiting game to see where it leads us.
