Hi Ludisia29 and welcome to the Orchid board
I'm afraid I don't know the Ludisia orchid and I've never tried pollinating any orchids but hopefully someone else will be able to help you.
It may be helpful to post a picture of your plant and the bits you think may be seed pods so that people can advise you.
Also you may get more answers to this question if you ask in the 'Propogation' sub-forum. From what I have seen in there, growing from seed is not an easy business, that's why there is a whole sub-forum for it.
Good Luck and welcome.
