First of all, I feel you, I have had problems with my in laws as well and it's very hard to deal with. You really need to stand up for yourself and your baby. You are pregnant and you cannot be stressed out at this point of your life. Have you tried confronting your in law? Maybe good communication can fix this problem.
Your baby is very important as well as your mental health. If proper communication cannot fix your problem, for the meantime, can you live with your parents? Your husband needs to understand that this thing with your in laws isn't beneficial to your baby and your health. He is your husband and he must learn to stand up for you as well.
I do think counselling is a great idea. Maybe a professional can actually help you two make an agreement regarding your case. I have never tried counselling before but I would if my husband hasn't stood up for us.
Good luck and take care!

I think if your situation is getting worse day by day then separation is the best solution for you. You have to convince your husband to stay away from your mother in law, as it will affect your child's health. I think he will understand as it is a matter of your baby. Otherwise, attend the counselling session.
