There are often young couples who have taken x-rays, chest x-rays, CTs, or have taken commercially available emergency contraceptives (such as Yutin), or have taken or used something vaginally, but have gotten pregnant unexpectedly, and then have a dilemma of whether they can have the baby in this case. In terms of the effect of pills or X-rays on the embryo in the month of menopause, there is an “all or nothing” phenomenon in medicine, either miscarriage (all) or no effect (nothing), i.e. the baby is fine; usually the effect of CT X-ray dose on reproduction is very weak and negligible. However, leaving aside the use of drugs or X-rays, there is also a rate of natural birth defects with no apparent cause. In summary, except for very few special drugs with strict contraceptive warnings, in case of the above, don’t get too hung up and choose to let nature take its course! Any time you get pregnant, there is a certain wind trap of birth defects, but not absolute, later to strengthen prenatal checkups, not to miss a lifetime of fate with the baby, or even regret for life!
