Post Weaning Cycles

DandelionAZO

This isn't a BF question exactly, but more of a post BF question. I am not sure where to ask, so I'll start here.

I recently weaned my 11 month old roughly 3 weeks ago.  I started spotting last weekend (2 weeks after weaning) for approximately 5 days, have had no spotting since and did not start my period.  Before this I had a period around 5 or 6 months pp, but nothing since.  I would like to start charting my cycles (either for NFP or TTC, not sure yet), but not sure what to do with this data.  Also, I have not recently taken a pregnancy test, but did take one roughtly 1 month ago.

Any thoughts on what this is all about?  Or similar experiences?
