It certainly could! Many recent studies have revealed links between women’s levels of stress and lowered chances of pregnancy. At the same time, stressed out women may also have less sex, or drink and smoke to deal with stress, which can lower chances of pregnancy.
The American Society for Reproductive Medicine states that little if any proof exists between stress and infertility, however unhealthy behaviors that often accompany stress can lead to infertility. If you’re feeling stressed out, try and get more sleep, remember to eat a healthy diet, keep smoking, drinking and caffeine consumption at a minimum and remember, the most important thing you can do in trying to have a baby is to have sex! Also, try and incorporate stress-reducing activities into your daily life, like yoga, meditation and exercise.
