need advice on NoID Phalaenopsis pods

[Nanuca]

Hello everyone! I am quite new to OB and to orchids too and I need your opinion on a little unintended experiment I started on February this year. I tried to self-polinate one of my NoID phal in order to practice a pollination technique I saw somewhere on youtube. I didn't expect it to work, but it did. So here I am, six month later with 5 large pods on my orchid. I read somewhere that pods should mature between 3 to 6 month, but those 6 months have already passed and my pods still look green, with no intention to ripen. My question is: is this normal? Should I wait more?
This is how they look:
