Replying to Dear Dr. NS

So today i was making my daily milkshake i always make, and after putting in all the ingrediants, i put the lid on and noticed the middle piece was missing. so i looked all over the place for it and gave up. I covered the hole with my hand. Once i stated to drink it i noticed little pieces just floating and thought nothing of it. Once towards the bottom, i had a very large piece of plastic in my mouth. I relieved that it was the middle piece from my blender. I imediatly threw up and counted to make myself for 2 or 3 times. The biggest piece i "found" was about the size of a penny. The biggest one, i think, i drank was probably the size of a pencil eraser in diameter, but there were pleanty of small ones too. I don't really know what to do. Call a doctor? pump my stomach? or if i should just take laxitives?

Spark notes**** i drank a decent amount of plastic and don't know what to do.
