During intercourse during pregnancy, abdominal pain during orgasm is due to abdominal pain caused by irregular contractions of the uterus during orgasm. If the abdominal pain is mild, it will not affect the growth and development of the fetus through proper rest. If the abdominal pain is more pronounced, it may lead to pre-eclampsia or inevitable miscarriage if it occurs in the early stages of pregnancy, or it may lead to pre-eclampsia or preterm labor if it occurs in the middle or late stages of pregnancy. When women are pregnant, they can listen to music, exercise and other appropriate distractions to ease the sexual urge. When having sex, pay attention to gentle movements, not too frequent, not too long, and try not to have an orgasm, so as not to have a negative impact on pregnancy.
