When a woman has a 35-day menstrual cycle, she can usually be tested for pregnancy around day 28.
Under normal circumstances, ovulation occurs on the 21st day of the menstrual cycle, and the fertilized egg is deposited in the uterus seven days after ovulation.
The body secretes human chorionic gonadotropin at this stage, and the blood composition can be determined by the corresponding blood test, which is conducted on the 28th day.
Women who are not using contraception are advised to pay more attention to the changes in their bodies and to go to the hospital for a detailed examination when symptoms of pregnancy appear, and to make a judgment based on the results and the doctor’s instructions in order to avoid other problems.
