Im so sorry you are going through that.. especially while pregnant.
Yes, stress can induce labor. Do your best to relax & maybe calmly speak to him about what you saw. Don't allow yourself to get worked up. If you do, it's time to take a break & walk away. You & your baby's well-being are far more important than his bs. Take care.
No, stress actually stops labor. But stress during pregnancy can cause other issues.
Stop worrying about him n worry about your child men come n go your child is forever remember thst
