Well over half of pregnancies deal with some morning sickness to some degree. It really runs a large spectrum. Some women are very lucky and just feel a little bit queasy here and there. Other women have the all-day sickness but most of the time it gets better shortly after that first trimester ends. There can actually be some validity to the old wives’ tale that morning sickness is a reassuring sign for a pregnancy. Typically part of what drives morning sickness are the chemicals associated with pregnancy and the hormone changes associated with pregnancy. If all is going well those pregnancy levels early on are driven higher and higher and lead to that sensation of morning sickness. So there really is some truth to that.
