HSV IgM test: You can't trust it at all. In theory, IgM antibody appears first and should indicate new HSV infection. But it's a poor test that should never be used in adults. (OK in diagnosing HSV in newborns.) Negative result means little, and positive result is often false. You should have had IgG testing as well; that's the test to rely on. If no symptoms of new herpes, probably all OK.

Still healing?: If the epididymitis was cleared by the antibiotic, the symptoms should have remitted by now. Possibly there is residual cord inflammation leading to persistent pain. You didn't mention if the physical exam was normal or not. Please see your doctor for an actual examination again, or consult a urologist to see what's going on.

Unlikely: If all testing negative, i doubt it. You may have simply not ovulated last cycle and that is why you are so late. Are your periods normally regular? Check with your obgyn and good luck.

False hematochezia: Certain foods can color your stool red and can mimic hematochezia (bright red blood in the stool):red gelatin or jello, popsicles, or kool-aid, tomato juice or soup, and large amounts beets. If the red stool persists after avoiding the culprit food item for a few days, it is wise to report this to your doctor for further work-up.
