Answer #1: Chezkas Taharah permits her to have Bi'ah as long as he did not divorce her.

Answer #2: [Due to Chezkas Taharah,] he need not divorce her until after the 11 days of Zivah pass.

Implied question: A pregnant woman is Dayah Shatah!

Answer #1: That refers to other blood that she sees when she is pregnant, but not Dam Leidah that she sees due to the womb opening.

Answer #2: Some explain that here is like R. Yosi, who requires three Onos (periods without blood until she is Dayah Shatah. She gave birth before this.)

Answer #3: She already saw once, and [the Tana] holds that on her second sighting she is Teme'ah retroactively 24 hours. He does not hold that pregnant women are Dayan Shatan for the entire pregnancy;

He teaches that even though through she saw this second sighting due to Ones of birth, even so she is Teme'ah retroactively 24 hours.

Question (R. Yakov of Orlins): Here it taught that Zavah or Shomeres Yom k'Neged Yom is Teme'ah retroactively 24 hours;

Even so, Rav Yehudah explained above that all 11 days she need not check;

Above (11a), we said that a woman with a Veses and the four women and a woman who passed three Onos [without blood] are Dayah Shatah;

A Tana taught there "even though we said that Dayah Shatah, she must check! (All the more so, during the 11 days, when she has retroactive Tum'ah, we should say that she must check.)

Answer: When she has a Veses, we can say that since Orach bi'Zmanah Ba (menstrual blood, comes in its proper time), she must check herself at the time of her Veses;

Also regarding the others, we can say that she must check lest she forget the law of checking [when she will be obligated to check];

[I.e. we are concerned for] Besulas Damim (one who did not yet see) when she will see, and a pregnant or nursing woman after the days of pregnancy or nursing will end, because they were accustomed for a long time without checking.

Implied question: A Zekenah (past menopause) will not come to need to check again. There is no need to decree about her!

Answer: Even so, we decreed about her due to the others.

Distinction: However, within 11 days she need not check, for it is a short time. She will not forget the law of checking. After the 11 days, she will check, and it is a short time since she checked.

Explanation: Not only in the actual days of Sefiras Zivah [she does not fix a Veses];

Rather, it connotes that even in the days proper for Zivah, even though she is not a Zavah and her Mayan is closed, she does not fix, e.g. she saw once within 11 days;

He argues with R. Yochanan and Reish Lakish, who say below that a woman can fix a Veses in actual Yemei Zivah, i.e. in the middle of counting [seven clean days after] Zivah, similar to "amidst Yemei Nidah" (which is after she saw Dam Nidah), and all the more so she can fix in days proper for Zivah (when she did not see yet, i.e. her Mayan is closed)!

Pesak: We hold like R. Yochanan against Shmuel, like it says in Eruvin (47b).

Explanation: She does not fix a Veses within the days of Zivah that she needs to uproot through three times as if she fixed a Veses in Yemei Nidah;

However, must she be concerned through fixing [a Veses three times] in Yemei Nidah to forbid a fourth time, even if the Veses comes in Yemei Zivah? For this we bring a proper proof that we are concerned.

Question: Perhaps due to the first sighting it is called amidst Yemei Nidah!

Answer #1 (Rashi): He infers from what he said "she fixes [a Veses] amidst Yemei Nidah." This connotes that the third time, which fixes it, was in the days of her Nidah

Inference: It is considered as if she saw on Rosh Chodesh.

Question (Riva, to Rashi): Why didn't he answer that the case is, she saw on Rosh Chodesh and the fifth of the month three times;

Now, it is truly in Yemei Nidah, and she fixed a Veses, and Dayah Sha'atah if she will see on the fifth of the fourth month!

Or, she needs to separate from her husband every fifth of the month, until she uproots her Veses three times!

Answer (Rashi): Above (11a), we establish R. Yochanan to discuss a closed Mayan, because we challenged the Mishnah, which teaches she need not check in Yemei Nidah;

Citation (11a) Question: She should check. Perhaps she fixes a Veses, according to R. Yochanan!

Therefore we establish R. Yochanan's teaching to discuss a closed Mayan. She saw the third time on the fifth of the month, but not on Rosh Chodesh. The third sighting was from a closed Mayan;

The Mishnah (11a) discusses when she saw twice on Rosh Chodesh and on the fifth of the month, and the third time, she does not check on the fifth when she saw on Rosh Chodesh;

This is because even if she would see, she will not fix a Veses, for the Mayan is open.

However, the first and second time she checks in the days of Nidah, lest she see the third time on the fifth of the month and not on Rosh Chodesh;

Therefore, he could not answer that she saw three times on Rosh Chodesh and the fifth of the month, for if so the Mayan is open;

Answer (cont.): Rather, he answered that she saw twice only on Rosh Chodesh, i.e. the Mayan was closed, and also the third time, even though she already saw on the 25th, what she sees on Rosh Chodesh is considered a closed Mayan;

This is like we answer, that this that she saw on the 25th was extra blood.

Answer #2: He infers that it is considered that she saw three times on Rosh Chodesh. If not, why did he say that she fixed a Veses? This sighting was unlike the others, which came in her days of Nidah!

Question: It is astounding to say here that she followed her initial pattern, and it is considered as if she [initially] saw on Rosh Chodesh, since she did not yet fix a Veses on Rosh Chodesh!

This is unlike above, when she already fixed a Veses on the 22nd, like it says "she was accustomed to see..."

Answer #3: It seems that the case is, she saw three times on Rosh Chodesh and the fifth of the month.

Implied question: Why didn't the Gemara mention three times?

Answer: We find so also above (11a), it did not mention three times regarding one who jumped and saw [blood].

Implied question: It says "now she saw on the fifth of the month, and she did not see on Rosh Chodesh." Is it not because through this sighting she fixed her Veses?!

Answer: No, she already fixed it through the first three times. Rather, it is to teach that she is Dayah Shatah for this sighting, like R. Dosa, who said above (4b) that she is Dayah Shatah only at the time of her Veses;

However, even without seeing now, we could have said that she fixed a Veses (through the last three months) to forbid her on the fifth of the month until she uproots the Veses three times.

Support: Now, it is proven that even though the fourth time she did not see on Rosh Chodesh, she fixed a Veses (i.e. she is Dayah Shatah) on the fifth of the month...

This is because since she saw three times on the fifth of the month, also the fourth month it is considered as if she saw on Rosh Chodesh. (Eizehu Mekoman - even though she fixed a Veses for the fifth in the middle of Nidah, and now it was her initial sighting, we consider it as if she saw like usual on Rosh Chodesh, and this was during Nidah.)

Similarly, we count 22 [days] from 22 [days from the previous sighting, based on when she used to see].

Explanation #1: We could have said "according to you, who establish R. Yochanan to discuss an open Mayan, if so the Mishnah (11a) is difficult. It says that she does not check in the days of Nidah!

Explanation #2: Alternatively, this is considered that the Mayan is closed;

He will explain a closed Mayan like Rashi said in Version #2 above (11a), that she saw the first four days of the month (there was no day without blood from Rosh Chodesh until the fifth of the month), and the Mishnah there discusses such a case. Then she does not fix a Veses.
