Likely: It is quite likely that you are fertile. Please note that even normal people may take a year of unprotected to get pregnant. Do see your doctor and start taking pre-natal vitamins before you try to get pregnant. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. Get HPV vaccine.

More fertile then no: At age 21, without contraception, the majority of women will be pregnant within one year. Your individual fertility may be different than above, but unless you desire conception at this time, reality testing is not a good idea.
