The choice to have kids is a personal one - whether you long for a large family or don't see motherhood as a milestone in your life plans.
However, many people start to feel the pressure to reproduce from their own parents.
According to a new survey by BodyLogic, women aged 31 to 36 feel the most heat to have a child, with 62% reporting that their own parents want them to start a family.
38% of women ages under 25 also get that expectation from their family - compared to 19% of men in the same age bracket.
The only age at which men were more likely to feel pressure to become parents was over 40.
The peak for both genders is the early 30s, with both men and women feeling the pressure in the aforementioned 31-36 age bracket.
If you're worried about your fertility, you're definitely not alone. The study found that 63% of women worry about their fertility.
Among millennials, 72% expressed a desire to have kids in the future.
