Whether it is normal to have yellow discharge for more than 40 days of pregnancy needs to be distinguished. In early pregnancy, due to the influence of hormonal secretion, it will show an increase in discharge, but there will be no odor and no vaginal itching or tingling sensation. Under normal circumstances, no special treatment is needed. Pay attention to hygiene and washing to keep the area dry and clean to avoid inflammatory infections. If there is yellow discharge, pain in the belly or falling, you should pay attention to exclude the occurrence of pre-eclampsia, you should check the progesterone in time, if the progesterone value is normal, pay attention to bed rest, do not exercise strenuously, pay attention to the peaceful nurturing of the fetus, because in the first trimester of pregnancy is the most important period of fetal growth and development, if the amount of exercise is too much, it will lead to the chance of miscarriage. If you exercise too much, the chance of miscarriage will increase.
