Don't care about most of the hot takes on fertility, if you are lifting weights regularly as a young woman, have a body fat around 22%, have a disease free body, if you feed yourself protein rich foods everyday with decent proportion of carbs and healthy fats, if you are experiencing a regular and timely menstrual cycle, if you are less neurotic about your life struggles in general, you are beating the probability of being infertile. Don't overthink it until you actually try getting pregnant and have a husband in your life. 

Stressing a lot about everything can alone destroy all the health progress you have been making as a woman, not joking, it's true.
