Pregnancy at the age of 20 in terms of both timing and natural physiology supports this decision. Women in their 20s are always ready to get pregnant and it doesn't matter if there's a delay.

Your chances of conceiving in one cycle in your 20s are about 45 percent (based on the average annual pregnancy rate per cycle). Most women in their 20s conceive within a year of having regular sex. As long as you’re in good health, your chances of conceiving within two years are about 98 percent in your early 20s, dropping slightly to about 95 percent in your late 20s. You’re very unlikely to have unexplained infertility in your 20s. Unexplained infertility is when your doctor can’t figure out why you’re not conceiving. But for women over 35, most infertility is unexplained. This has a lot to do with the decline in egg quality as you age. In this article, we’ll provide some helpful information to help you figure out your age and fertility when you get pregnant in your 20s.
