Stomach parasites are parasitic organisms that inhabit the stomach or intestines of humans, often causing severe discomfort, and in some cases leading to death.
Morning sickness occurs in 50 to 80% of new momâs to be. Itâs unfortunate that for many, the morning sickness will strike all through the day and not just in the morning. Most cases of morning sickness start between the 4th and 6th week of pregnancy and lasts until the 14th to 16th week. An easy way to calculate this would be 5 or 6 weeks from the first day of the last menstrual period.
How long morning sickness lasts may actually be different for every woman, and different for each pregnancy. Morning sickness typically lasts until sometime between 12 to 18 weeks of pregnancy, and then it just stops. It normally starts about two weeks after the missed period and lasts through the first trimester. Some women will have ongoing symptoms that seem to come and go for about one month in to the second trimester.
