I believe it might be able to. But im not sure. Miscarriages happen for a number of reasons. Not just one. You should look that up though. I dont think it can cause one, but its not good to stress too much. I know that if you stress and your further along than the baby really feels the stress too. And its not good for anyone whos pregnant.

Stress can cause a miscarriage but they said it has to be a high amount of stress (ie, ur mom passing away or something huge) but 60% of the time, miscarriages are caused by blighted ovums.. Hope I helped!
