I think my baby orchid may be slowing dieing? Help. Please?

I was given a baby Phalaenopsis Orchid as a mother's day present, the horticulturalist gave it to my fiancee because it is supposed to have it's first bloom around the time my first child is going to be born. Ok, that being said it is a TINY plant and it originally had 4 leaves and a spike that was healthy with many nodes. Over the past week, every leaf has turned yellow and dropped. I now have NO leaves, but the spike remains and it is green and seems healthy. The roots are green and they seem healthy too. Here's some background info.--I water every 6-9 days a little bit, the plant is in a clay pot with a drainage hole at the bottom, the plant also receives orchid food once every 10-12 days. Any advice from someone that knows orchids would help because I have been reading conflicting things such as this might be a fungal infection, to this is normal and this is because the plant is growing? I have no idea but I would like to save this plant if it is indeed dying. Thanks
