A
tzilum rechem is known in English as a hysterosalpingogram (HSG). However, doctors do sometimes perform
hysteroscopy for the purposes that you mention.
1) In either case, bleeding can be attributed to the
procedure and does not render you
niddah. Blood can be disregarded for a couple of days following the procedure. Following that point, we recommend wearing colored undergarments and taking precautions regarding stains, so as to avoid any possible questions. (For more information on stains, please see our articles "
Stains" and "
Toilet Paper".)
2) Yes, you should perform your
bedikah in the morning before the procedure and use pantiliners/colored underwear afterwords.
3) Mikveh immersion after the procedure should not present a halachic or medical issue.
4) Both halachically and medically, you should resume relations when you feel comfortable doing so. You may find yourself sore after the procedure. Even if delaying relations, you may immerse for the purposes of other types of physical closeness, so long as you and your husband are careful about
hotza'at zera levatalah, spilling of seed.
We wish you a smooth and successful procedure!
