Gilui Arayos as is known is one of the 3 "big avaros" that one has to give up their life for. Is the prohibition of a Niddah considered forbidden to the extent that one would have to give up one's life to avoid violating such a prohibition?
Update: Since there seems to be a discussion in this I'd like to pose another question. According to the one that holds it's not in the category of gilui arayos is it possible still that a niddah is still considered to be an "ervah"? Or do the 2 for sure go along (I heard this point discussed by someone and seems there would be nafkah minas. A possibility would be that we say ein davar sheberva pachos mishnayim, however by a niddah the isha herself is believed -- eid echad.)
