I asked (no.289) about mikveh after hysterectomy and you said there’s no need but what if I was a niddah before hysterectomy what do I do now? Do I have to do bedikos before mikveh? Thanks
If you were a nida before you had the operation, then you do have to go to the mikvah, because a woman cannot become tahor unless she goes through the tahara and mikvah process. Therefore you would have to go to the mikvah, however regarding bedikos, you should just make a hefsek tahara, and then count seven days and then you can go to the mikvah. There is no need for you to do the bedikos of the seven days because the hysterectomy caused that we know that you will not have menstrual bleeding now. Since you were a nidah before the operation, you should do all the normal preparations and be tovel in the mikvah with a bracha.
