My Patagonian Conure strange behavior! Should i be worried!? HELP!! :(?

hello! my dad bought me a conure parrot today..he is 8 months old ..when he first got here he reacted normally frightened as his first time in the house but then later he started playing and having fun and i have noticed that he regurgitated whenever im near and I've searched this behavior and it turned out fine and normal because it is a sign of affection!! the important thing is, just a couple of hours ago i went to check up on him and it seemed that he was regurgitating at first but then he vomites this white substance with lil round pieces (food like)! and the weird thing is he starts to eat it and then vomit it again!! he did this several times in a row just throwing up and eating it again!! he drinks water normally and he ate a little bit today! so is he sick!!? im so so worried and the vet is closed now and its very far from my home!! what to do!? :'(
