2,136. Giving Birth Nowadays
Hilchos Issurei Biah 11:5
Similar to the previous halacha, any woman who gives birth nowadays is considered to have given birth as a zavah and must count seven clean days. The accepted practice in Babylonia, Israel, Spain and the West is for a woman who sees blood in the days following childbirth to count seven clean days after the bleeding ceases. This is so even if she already counted seven clean days and went to the mikvah. She has no pure days. Rather, whenever a woman sees blood – whether it’s from childbirth or pure blood – it is all considered ritually unclean and she must count seven clean days after it stops.
Hilchos Issurei Biah 11:6
It was the Geonim who enacted that there would be no pure blood. The stringency that women accepted upon themselves in Talmudic times only meant that a woman who saw blood that would render her ritually unclean would have to observe seven days; blood that was seen during her pure days after counting did not raise any concerns because the pure days are not subject to niddah or zivah as has already been addressed.
