Except in the very specific circumstances of
dam betulim, bleeding from hymeneal tissue
does not make a woman niddah.
You can generally avoid questions altogether by being careful with the "Precautions for Marital Relations" outlined on our page on
Stains. Please also review our page on
bleeding and marital relations; in general, blood could be attributed to the hymen tag and would not make you
niddah.
Ultimately, this is your decision to make. You may find that taking care of it now, generally a straightforward procedure, will save you trouble later. Or you can wait and see if it in fact causes trouble.
Please write back with any further questions.
