for cleaning: use a vinegar solution to help get rid of the smell. i agree with you in that i'd wait the 2 weeks before messing with her too much (if the smell will allow it).
my only ever regurge happened with Yellow when i had an ambient heat spike a year or so ago. it hadn't lasted more than an hour but that was still long enough to stress him out to that point. i waited the two weeks out and he's been a good boy ever since, but i was TERRIFIED after that, tho. i literally thought i might have killed him and i was waiting to come home and find a corpse. it was traumatic for us both, but we managed to pull through.
as for the reason why it happened, i can't help you there. i'm sure this all would be easier for you if you knew what happened. just know that regurges do happen sometimes (and for a reason), it's terrible, and you must try your best to learn and avoid it in the future (you already are).
beeps bounce back 100% if proper care is provided in the aftermath.your noodle will be just fine.
