Woman in istihaadha performing asr and qadha of zuhr with the same wudhu

Today was my max day for menses. I was supposed to do ghusl at 6:27pm but the bathroom was in use so I ended up doing it a few mins before asr began (I was in the bathroom at 5:51pm and asr began at 5:55/5:58pm). I finished ghusl after around 20-30 mins after began. I’m in istihadah. I dried my hair then read qada of zuhr and then I read asr with one wudu. Is this fine?
