Itching of the vulva in early pregnancy is often caused by vaginal inflammation, mainly due to decreased resistance during pregnancy or increased vaginal glycogen secretion due to thousands of times increase in estrogen in the body, so it can easily lead to Candida reproduction and cause Candida vaginitis, which will manifest as redness and swelling of the vulva, unbearable local itching, and vaginal discharge that is like tofu sludge. It is recommended to wash the vulva with 5% sodium bicarbonate and to wash the vaginal opening to change the local pH and inhibit the growth of Candida, which will relieve the symptoms clinically. Vaginal pills should not be inserted in the early stages of pregnancy. If vaginal pills are inserted, it may lead to the possibility of pre-eclampsia or inevitable miscarriage.
