OP says WAS feeding twice a week 'at times', so it may have been a thing done in the past. While still not ideal, if this isn't something haven't done for a significant amount of time, then it may not be the issue. OP sounds aware that their snake is a healthy weight now, so it reads to me like they aren't feeding twice a week anymore...
Can you elaborate if your bp had already been fed once this week before the regurg? (Is this a thing of the past now?) Otherwise people will keep telling you that was the cause!
With any regurg, it could be a multitude of factors, as others have mentioned here. If you aren't feeding twice a week anymore, then your idea is a valid one. Best hold off feeding for a few weeks, then feed a small wean again later. If they regurg again, then take them to a herp vet to discuss it. Hope your bp is ok!
