For most people, getting pregnant does not require anything specific apart from having sex with no contraceptives. Young people can achieve pregnancy pretty easily if they have no medical issues which could affect their fertility. Some people prefer to track their fertile days in order to conceive, or do ovulation tests although it’s not essential.
A good balance of healthy diet, exercise, and enough sleep can maximise fertility. If you want to know if you are healthy to conceive, consult your doctor.
