While the initial bleeding from the
biopsy was considered
dam makkah (blood from a wound), which does not render a woman
niddah, the extended bleeding you are currently experiencing is uterine bleeding triggered by the progesterone and not caused by a wound. Therefore you were rendered
niddah from this bleeding.
Once the bleeding stops you should perform a
hefsek taharah and count
seven clean days before
immersing. If you continue to experience staining, or if the
bedikot are causing discomfort, please be in touch with us or your local posek about reducing the number of
bedikot.
Please feel free to get back to us with any further questions.
B'hatzlacha!
