Fever and achey body are part of your immune system responses. It sounds like those came and went, which is a good sign. Women can release old dead uterine tissues and this will sometimes involve clots.
Mucous cells are part of your body's immune response, as are NETs (neutrophil extracellular traps). NETs look like nets. They are created by the white blood cells (neutrophils) to trap fungus, bacteria, and yeast. They are an effective response against the branch-like structure of fungal candida. Many people mistake them for candida when passed in the stools. They have a whitish appearance. If you have ongoing concerns, you should have it checked out. An MD probably won't have much to tell you, reflective of his education and knowledge, and just throw antibiotics at it. If MDs weren't able to prescribe medications would they be in business? Probably not, except for emergency medicine and surgery.
