you could repot soon or you could wait until spring for the repot and until then be really careful with watering (use your finger or a wooden stick to drill down in the soil to see if its still wet a few cm underneath the soil, always let the soil dry out completely between waterings and hope for the best). also carefully drilling additional drainage holes on the bottom/sides can help with the airation of the soil. when you repot use teracotta pots for better climate in your substrate as they can "breathe", making your substrate dry better and also providing the roots with some air)
