TMI question....

Ok TMI question. Had miscarriage in Oct right, then normalish AF about 5 weeks later so thought things were back to normal but then last month had early AF like about 3 days early I think it was...waiting to ovulate this month and have had no signs of it but now bleeding again, and it is only like day 16 (normal cycle length 26 days) What is going on? Or is this to do with DS (aged almost 2 and only having milk at night)weaning and cycles will be a bit weirdo for a while, or coz of miscarriage? My cycles are pretty much bang on 26 days and have been for AGES, like about 18 months. Could be ovulation spotting as have noticed that I have had that for about a year, but then am ovulating late too as normally about day 11-12, but would I be ovulating late this month since AF was early??? Anyone have any idea?
does that even make sense haha!
