question about early AF

Ok TMI question. Had early miscarriage in Oct, only just past 5 weeks, then normalish AF about 5 weeks later so thought things were back to normal but then last month had early AF like about 4 days early I think it was...now this month am bleeding again and it is only 16 day cycle(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.

I have noticed for about 10 months that I get ovulation spotting but this is heavier than that but not a normal period either and have had no other signs of ov.

This really sucks coz thought with early miscarriage would be back to normal quickly so we could keep trying but blah, no chance. I don't want to wait another flippin year to get pregnant again

Thanks Monkeys, I didn't have the bloods til the levels were at 0 but today went to the Dr and he has ordered me 21 day bloods to see if I am ovulating properly.
