Zohar vaikra 97 (raya mehimna) sefira is like tumah of wife (quotes passuk of zavah countinting) even after blood stops needs to count ofr complete taharah so too jews left mitrayim ended the sibah - cuase of tum'ah but were still tamei till they counted 7 completely clean weeks.
If like zavah what happens to someone who is nichshal during the seven weeks ? one drop of dam is soser the whole count! - does such a person have to restart & miss matan Torah?!
Kdai R' Shimon L'smoch alav b'shas had'chak. Ein L'cha shas d'chack gedolah mizu.
R' Shimon les lieh Muktzeh. We know he agrees to some - chisaron kis, mius, issur etc... But he is matir if there is no positive cause for haktza'ah or whenever the cause of hak'tza'ah is removed. He doesn't hold of migu d'iskatzoi bein hashmashos iskatzoi kula yoma.
only when the sibah of rejection & tumah is still present does he hold that one can be pushed aside, -muktzah. But just because of an earlier state of tumah will not cause one to be pushed away now.
although in general we don't paskin like him in muktzah, K'dai lismoch alav bshas had'chak.
The problem still is that dam in the 7 days is cause for tumah & reverses all!
If we have the midah of hod we ADMIT our guilt we can say ritzoneinu L'asos ritzoncha, umi me'akev? S'or sheb'isah - yetzer & shibud malchiyos. Our sin is not really coming from us but from other sources. Dam not from the mekor is not a cause for tumah. It is a stain we can be toleh on another source, a bug or wound.
Then we may use the midah of hod again 'back to back' (hod sheb'hod) to THANK Hashem for the opportunity of teshuvah & cleanliness, and anticipate with simcha kabolas haTorah in purity.
