Help identifying parasite

Does anyone know what these are? The toilet was filled with them. I've lost over 60 pounds in the last three months and I'm now narrowing it down to a parasite. These came out and many more besides what's in the picture after drinking vitamin water w acai juice. I'm now waiting for testing from the hospital. I'm just worried that they won't find anything in the samples I gave them. If you know what these are please help.
