Does this phal need repotting?Non stop blooming.

[gabrielacocinera]

Hello
I am wondering if this phal needs repotting. It has been making new blooms non stop since November. Once the old blooms are dying new ones are emerging from a different stem. I've been wanting to re-pot but read that doing so during blooming is a no no.
To me, it looks pretty root bound. But I am not sure.
It appears that there are new blooms forming on one of the stems right now.
The main stem has been on this phal for well over a year, maybe two, as it never died. I just left it there since it was green. Now I have a forever blooming phal that might need repotted.
Is it normal for these gals to bloom nonstop for this long? Should I be worried and cut her back? I usually let my plants do as they wish and everything turns out growing like crazy but when it comes to orchids I don't know that much.
I've attached some photos. The one with new blooms is a little fuzzy since I took it with my tablet.
Thanks for any help.

Rootbound phal??
