1 A woman giving birth: even if she has not seen blood, is ritually impure as though she were a menstruating woman; whether she delivered a live child, or whether she delivered a stillborn child and even if she miscarried. And how many are the days of her ritual impurity? Now, in this time, all of the childbearers are considered as those delivering in a flow and require to count seven clean days; it follows to say that one who delivers a male sits seven for the birth and seven clean (day)s for the blood-flow, and one who delivers a female sits two weeks for the birth and seven clean (day)s for the blood flow. The days of birth, which are 7 for a male and 14 for a female, if she did not see (any blood) on them, they count for the accounting of her blood-flow; and if seven clean days are completed within the 14 for a female child, such a woman is forbidden until the night of the 15th (day); and if she had immersed prior to that, the immersion does not count for her. Rema: And after 7 for a male and 14 for a female, she is permitted to her husband immediately, on account of the fact that she had counted seven clean (day)s and she did not further see (blood-flow). Nevertheless, there are places where the custom is that they do not immerse within 40 (days) for a male and 80 for a female (Beit Yosef citing the Mahari"k, who brought the tanya, and in the Agudah ch. A"P (Arvei Pesachim?) and in the Mahari"l), and one ought not be lenient in a place where they were accustomed to be stringent (Riv"sh); but in a place where there were no set custom, one ought not be strict at all - just as soon as she has not seen blood after the seven for a male and fourteen for a female, and has counted seven clean days, she is permitted to her husband (T"H - Torat haAdam? - section 255). But if she has once again seen, even a drop of blood the size of a mustard seed, she is ritually impure - even though according to biblical ruling it is pure blood - the custom has already spread throughout all of Israel that we do not engage in sexual relations over pure blood (Beit Yosef, and Agur, and Tur, and decisors citing the geonim), and its ruling is like the other cases of blood in every way.
