Hi hun! Hmmmm, all I can say that post birth of my DS my periods have been different too, in terms of length and cramping too. Cycles are slightly shorted too, going from 29 days to 27-28 days. I also used to get really awful AF cramping prior to having DS but sine I've had him my cramps have become less painful. The bleeding you're having sounds a bit odd (especially with no cramping whatsoever) , but then again maybe your body has changed sine you've had your DS?? I always say, if in doubt, check it out! Go and see your GP is the bleeding continues hun as you could become anaemic. GL
