Thank you for this very helpful resource.

I understand that even the tiniest dark speck on a bedika cloth must be shown to a Rav but I almost always notice some sort of speck, maybe because I examine the cloths very carefully (should I not be doing that?). It's usually obvious that it's not blood but just dust or a fiber from clothing. When I show these specks to my Rav, they never turn out too be blood (and he usually comments on what good eyesight I have).

I feel silly showing them so often to the Rav and, based on conversations I've had with other women about this, it seems that most women either don't look at the cloths so carefully or don't show such miniscule specks to their Ravs. So, a few days ago, I it was day 5 of my shiva nekiim and I saw one of these very tiny specks and decided it wasn't worth showing the Rav and discarded the cloth. I mentioned it to my Rav later and he said that if I thought it was a clothing fiber, it was fine. The problem is, I don't know if that's what it was, but it definitely didn't look at all like blood and most women probably wouldn't have even noticed it. I've since been to the mikveh and am feeling that I may have done the wrong thing (I know that transgressing the laws of niddah is very serious). Am I being unnecessarily concerned?
