4th HW cleanse, "cucumber seeds"

Hi everyone.

I'm on my 4th HW cleanse. The first 3 were 4 months apart, and then I waited 6 months to begin this one. I am on day 12. Today I started passing, for the first time ever, these things which look like cucumber seeds.

I had read about these before, that they were tapeworm segments.But if that's the case, then why didn't I pass this tapeworm in one of my previous cleanses? Or is it possible that I actually picked this one up AFTER my last cleanse?

This is weird. Not an emergency question to be sure, but if anyone has any insight, I'd appreciate it. Thanks.

Jo
