Spontaneous abortion after 40 days of pregnancy, patients need to ensure their own rest, be sure to get enough sleep, strengthen nutrition in their diet at ordinary times, pay attention to personal hygiene, keep the vulva clean and dry, and prohibit sexual life within one month. I suggest you go to the hospital for a B-ultrasound examination in a week or so to see if there is any residue in the uterine cavity. If there is no problem, it will generally not cause gynecological inflammation.
