Is there a big chance of pregnancy?

According to what you said, the probability of pregnancy will be high, but it is not 100% pregnancy.

Pregnancy is a complicated physiological process.

Pregnancy is a complex physiological process, and the following conditions must be met: the ovary discharges normal eggs, the semen is normal and contains normal sperm, the eggs and sperm can meet in the fallopian tube and combine to form a fertilized egg, the fertilized egg is successfully transported into the uterine cavity, and the endometrium is fully prepared for the implantation of the fertilized egg. Any abnormality in these links will affect the pregnancy rate.

School-age mothers have a high probability of getting pregnant.

If there is no infertility factor and the examination is normal, the pregnancy rate of school-age mothers (23-30 years old) is 30%-40% within three months, 50%-60% within half a year, and the pregnancy success rate reaches 70%-80% within one year.
