I Got White Eggs/worms In My Period. What Does It Indicate?

For the first time ever I noticed many little possible white eggs (or maybe worms?) inside each menstrual blood clot. Are they really eggs/worms?? what should I do? I had bacterial vaginosis so i took metronidazol orally twice a day for 7 days. Since it did not cure me, a week later I began to have it in gel form inserted directly into the vagina once daily for 5 days. Then I began to get more discharge and even tiny cheese-like little white discharge. And now today, two weeks later, I got my period with problems as described above. Oh one last detail, my gynecologist also prescribed me Primadophilus Bifidus from Hihealth while taking the gel form of metronidazol... and I still am today. Could that be the cause of my problems???
