I am a midwife. Your bleeding could be one of two things. Since it has been five weeks it could be your first period, especially if you are not breastfeeding. The other likely scenario is that you are doing too much (easy to do with three other children.) Your uterus has a wound on it the size of the placenta. It essentially scabs over and heals up. However, if you are up running around a lot that scab can tear away and your bleeding will begin again. Also, the cramping is normal. It does take a full six weeks for the uterus to completely shrink back down and the cramping is the uterus doing this. Or, if it is your period you could be cramping from that.
