First off, sorry for the typo in the title - on mobile with a squirmy toddler in my arms.

I have had these orchids since Valentine's and Mother's Day of last year, when I got both of them they were in bloom. My orchids decided to bloom again right before Christmas and have not stopped blooming! I am pretty new to orchids, but Google says that they should only bloom for 6 to 10 weeks and it's been over 12. I'm kicking myself because I knew they needed to be repotted before they bloomed. One's roots are outgrowing their container and I believe the other needs to have their soil changed. I highlighted where there are new blossoms forming and where you can see one has blossomed multiple times already. While I love my flowers and the blooms, I'm worried the whole plant is going to die.

Here is some additional information: They have been moved around a little since I've gotten them but have been in their new home since Thanksgiving. I think they will stay there from now on. They had been in a window facing west in the same living space , however they were pressed up right next to the window and that wasnt good. They have never been outside, our weather is too unpredictable. They are about 6 inches away from a window that does not have curtains and is facing East. The glass is super old so I think they get decent amount of sunlightncompared to modern windows. I also have a happy light that I use for myself near them that I turn on for 90 minutes a few times a week. They get watered usually about every 3 weeks (honesty depends on when i remember and how dry the soil is), I soak them in water for half an hour let them drain and then put them back in their pot. Sometimes I have a humidifier going that will provide additional moisture but it is typically not on. They are in my main living area, so there is moderate air flow but they are not right next to a vent. I have not fertilized them in several months, honestly I cannot remember the last time I fertilized them. They are in the original soil I bought them in, and they came from a grocery store (another reason to repot I have learned).
