Poor you rorylex, thats sounds like alot of bleeding.
I bought about 2 packs of the stayfree thick things, and 2 packs of libra ones. The maternity unit gave me like a pack of 5 cotton swab things that were tiny and useless, but straight after my shower my MW made up a nappy thing of those blue sheets of stuff that catch everything when your on the bed, etc and 2 of the crappy mat unit ones which held everything in. I felt like a bit of a dick but it worked well.
After the first few hours I went straight into the stayfree pillows the I think by the time I went home I was using libra ones. I have 1 unopened pack of stayfree and have the other pack still left. Bt I think my bleedig was veeeery light compared to most.
