Nausea may be related to the increasing levels of hormones released during pregnancy. Experts do not know why some women develop nausea while others do not.

No one knows for sure what causes nausea during pregnancy, but it's probably some combination of the many physical changes taking place in your body. Some possible causes include:
• Rapidly increasing levels of the hormone human chorionic gonadotropin (hCG) during early pregnancy. No one knows how hCG contributes to nausea, but the timing is right: Nausea tends to peak around the same time as levels of hCG.
Estrogen, another hormone that rises rapidly in early pregnancy, is also considered a prime suspect, and it's possible that other hormones may play a role as well.
• An enhanced sense of smell and sensitivity to odors. It's not uncommon for a newly pregnant woman to find that she's overwhelmed by the smell of a bologna sandwich from four cubicles away, for example, and that certain aromas instantly trigger her gag reflex. This may be a result of higher levels of estrogen.
• A tricky stomach. Some women's gastrointestinal tracts are simply more sensitive to the changes of early pregnancy.
You may have heard that morning sickness can be caused by a vitamin B deficiency. While taking a vitamin B6 supplement does seem to help ease nausea in many pregnant women, this doesn't mean they have a vitamin deficiency. In fact, at least one study has shown no significant differences in the levels of B6 in women with morning sickness and those without.
No one knows why B6 is helpful. There's also some evidence that taking a multivitamin at the time of conception and in early pregnancy helps prevent severe morning sickness, but again, no one knows why.
Some researchers have proposed that certain women are psychologically predisposed to having nausea and vomiting during pregnancy as an abnormal response to stress. However, there's no good evidence to support this theory. (Of course, if you're constantly nauseated or vomiting a lot, you certainly may begin to feel more stressed!)

Ususally somewhere around 5 weeks, when the HCG hormone is pretty high. Although there are some women who never get sick. The hormone starts to drop off at 12 weeks so that's when the nausea usually subsides, but then there are women who are sick a lot longer.

for me I was feeling sick before I missed my period, so probably within the first week of conception. I wasn't throwing up but I was getting dizzy and just feeling really off and tired.
But my mom didn't start getting sick until her 4th month, you just never know.
