To repot or not?

[Neophyte2017]

Hi there,

I’ve had some success growing a couple of orchids but am still a beginner. My husband bought me a mini orchid for Valentine’s Day. The leaves are light green and limp and I looked at the roots and it looks like some look good but some are brown...see pics below. Last time I bought an orchid I repotted it immediately and lost all of the blooms and it hasn’t rebloomed yet...I was going to wait until it stopped blooming before repotting this time but between the brown roots and limp leaves I thought repotting it and cutting off the bad roots might be needed. Any suggestions on what I should do? Anything would be much appreciated! Thanks!
