1,087. Bleeding as a Result of Intercourse
157:6 If a man marries a virgin and consummates the marriage, even though she may bleed during the act, he should nevertheless finish as one normally would, without any concerns. After they have finished, they should separate and she is ritually unclean. Even if they didn't see any blood, we are concerned that perhaps a drop of blood came out and was concealed by his bodily fluids. Therefore, she is fully considered to be ritually unclean.
157:7 If a virgin went to the mikvah after the couple's first marital relations, then she saw blood after their second, third and fourth times being intimate, an authority must be consulted to evaluate whether this couple is able to remain together.
