I dont know if you guys have the brand there, but here we have libra goodnights with wings, they are also designed for maternity use and are thin pads, but the soak up really well......
As for post partum bleeding it normally lasts from 2-6 weeks, first heavy some times with clots, any clots larger than your thumb nail in the first few hours should be shown to a nurse just in case.... After the first few days the bleeding should go to about the same as a period, then gradually go lighter and become a browny colour, if you bleed for 4 weeks, generally the bleeding after four weeks may get a little heavier because it will be your first period since the birth, after that you will be normal again, and can start using tampons again for your next period.
