Quoting milo456:" If you had really bad periods pre baby, after having a baby do they get better or worse? Im 16 weeks pp and have yet to have a pp period, but they used to be hell, does anything change at all?"
I had horrible periods as a teenager and into young adulthood. After having my 3 older children, however, my periods were great (if you can say that about a period.) They were pretty regular (27 to 34 days) and they lasted about 3 days total, with only one day of really heavy flow. Some months I had cramping and others I didn't. My periods have been worse after having this last baby, but I think it's probably due to my age (I am 43).
