Progesterone values rise slowly in the first trimester and peak in the late trimester. The normal value of progesterone for women in the follicular phase is 0.6-1.9 nmol/L, and the normal value during ovulation is 2.40-9.40 nmol/L. Usually live a regular diet, ensure sufficient sleep, relax, eat a light diet, try not to eat cold, spicy and stimulating food, and drink more water.
