Research suggests that nausea and vomiting during pregnancy might be due to the effects of a hormone produced by the placenta called human chorionic gonadotropin (HCG). Pregnant women begin producing HCG shortly after a fertilized egg attaches to the uterine lining. Women with severe morning sickness (hyperemesis gravidarum) have higher HCG levels than other pregnant women do. Women pregnant with twins or multiples also have higher HCG levels and are more likely to experience morning sickness. Similarly, estrogen, another hormone that increases during pregnancy, is associated with an increase in the severity of nausea and vomiting during pregnancy.
However, high pregnancy hormone levels aren’t consistently associated with nausea and vomiting.
It’s also possible that nausea and vomiting during pregnancy are signs of viable placental tissue.

im not sure how this could be done, but maybe balancing the production of those hormones?
In the mean time a few loops of the Spleen one can ease up regular nausea
