Mazal tov on your upcoming wedding!
It is not sufficient to assume based on your medical history that you do not have a hymen. However, if your physician is certain through examination that you have no remnants of a hymen or chance of hymeneal bleeding, and that the absence of the hymen is partially attributable to the frequent examinations, then you would not
become a niddah automatically the first time you have relations.
We suggest refraining from
physical contact in public after you are married so that the situation remains private.
If you do have some remnants of a hymen, or if you find blood after first-time relations, the usual rules of
dam betulim apply.
