continually blooming spike-to cut?

[BigRed]

I have a really cute little unknown phal. It was labeled sweetheart phal (yeah that helps) when I bought it. After researching on the internet I believe it may be
Doritis pulcherrima x Phalaenopis decumbens or related hybrid. It's leaves and spike are a vibrant lime green. When in bloom it had several branches with little flowers and the main bloom on top was like a flower cone. I don't have any pictures so thats the best I can describe it. Its been out of bloom for months but I haven't cut the spike. I cut the branches off because they stopped producing but the tip keeps trying to grow flowers. When the bud gets to be the size of a popcorn kernel it turns yellow! it's frustrating watching a new bud grow and die every few weeks.
My question is should I cut the spike? It's not growing anything successfully. I'm worried that not chopping it might hinder the plants development of future spikes. The plant seems to be healthy. Its grown one leaf and is starting another since the blooms fell. I just want to ensure a beautiful show next time.
