Hi ... I Had A Woodfired Pizza Today, And It

hi ... i had a woodfired pizza today, and it was quite big. I somewhat ate it fully. After which i had some pear juice, the moment after, i suddenly got a struck of pain right on my lower chest, which hurt for about 10-15 min. I burped quite a few times and the pain eased. Now the pain is gone, but i still feel it now and then when i drink water or eat something. Later on, i started spitting some orange coloured blood. Have I overdone myself? Should i be worried?
