I am 32 weeks pregnant. i have been under so much stress lately. i have been crying alot. i an worried about my child. can this harm my baby?

Not much: Your stress and state of mind can certainly alter your diet & sleep habits and have minor effects on the nutrition baby gets. Baby might end up a few ounces lighter at birth. Luckily the system is designed to protect baby from your issues & draw off nutrients from your bones & diet if you have a poor one. The baby also doesn't know if your laughing or crying.
