So Long Story Short,I Basically Ate 3 Pieces Of This

So long story short,I basically ate 3 pieces of this cake which (I didn't know was 8 days old) so I freaked out and decided to throw up on purpose so I did ,but on the very next day until now I am constipated and feel bloated Everytime
I DON'T feel pain or acid reflux I just feel bloated and constipated all the time
What could probably be the cause?
Should I take probiotics, digestive enzymes or HCL with pepsin?'. Please type your question here...
