My foster BP is on a 2 week schedule for feeding, and generally poos about a week after eating. He does urates at least once a week though. The other fosters were on weekly feedings, and usually pooped the day before or day of their next meal.

That's good that he recently defecated. If he is of good weight and seemingly healthy, if it was my snake, I would wait an extra week or two before feeding again. When they vomit, they are losing some of their natural gut flora, and it can take some time for it to regrow. He probably didn't lost very much with that little thing, but to me, I'd rather wait a little than risk feeding too soon and causing another regurge.
