There is a tradition in Orthodox (not Conservative) to keep niddah like a zava- meaning 4-5 bleeding days and then 7 additional clean days. In the Torah, niddda is 7 days and then mikveh. This was the way it was until the expulsion of the Jewish people when it was felt that people would get confused with the counting for niddah. My question is if the woman went to mikveh after the 7 days, is it ok bedieved? Thanks.

I disagree with your assertion that it is (a) a tradition and not a halakha, (b) that only Orthodox and not Conservative or other Jews practice, and (c) the reasons behind the 5 clean days. Under all of that, though (and the inconsistent spelling), you have a good question. Can you try revising it a bit? – Charles Koppelman Sep 22 '13 at 18:57
@CharlesKoppelman בנות ישראל החמירו על עצמן שעל כל טיפת דם קטנה כחרדל יושבות הן ז' נקיים כמו זבה גדולה. That sounds like a tradition to me. But that's not really the subject of this post. – Robert S. Barnes Sep 22 '13 at 19:53
@CharlesKoppelman וסיבות רבות לחומרה זאת, והחשובה בהן היא כדי שתהיה לכל הנשים ספירה אחידה, ולא תצטרך כל אחת ואחת לחשב לעצמה חשבונות מסובכים שלא כולן בקיאות בהם. – Robert S. Barnes Sep 22 '13 at 19:59
@Robert Charles is right. You are ignoring the issue of Poletet shichvat zera. Plus something that started as a tradition may still later be formally enshrined as law – Double AA Sep 23 '13 at 5:40

If the woman did a "hefsek taharah" (meaning she checked herself and was clean) before immersing the Mikva, then M'Doriasa (according to Biblical law), she is okay. But according to rabbinic law, she is still a niddah until she counts seven clean days and then immerses.

What is the implication of not keeping the de Rabanan in this case? There is obviously not the issue of arayot or karet. – Robert S. Barnes Sep 22 '13 at 1:36
How does she know when the seven days are over? what if day "1" wasn't the right color red and was pure. – Double AA Sep 22 '13 at 3:21
Because of that question, Chazal were gozer to keep seven clean days. But it seems to be only a chasash d'rabanan. – Reb Chaim HaQoton Sep 22 '13 at 7:34
@DoubleAA The assumption in the question is that we know it to be nida M'Doriata. – Robert S. Barnes Sep 22 '13 at 18:30
@Robert You can assume whatever you want for arguments sake, but practically no one knows how to distinguish the different colors of red anymore. It is just a lost tradition that you would need a prophet or something to restore. – Double AA Sep 22 '13 at 19:18
