Honestly for me I just let the tears come (when I'm alone). I always feel less stressed after I cry. Your body releases stress hormones through your tears. My personal way of relieving stress.
It takes extremely large amounts of stress to cause any actual problems with the baby. I know many women who have lost family members, parents or their spouse while pregnant without harm to the child. It's not ideal of course, but stress is a natural part of life. Best thing is to take things as they come and not worry over what you can't control.
Thank you! I'm a ftm and worry about everything especially since I had a misscarriage 5 months ago.
Worry is natural, just don't let it consume you. Enjoy each day you have.
