during my pregnancy my husband and i had some fights too. stress is natural when you are going through this, especially for the first time. the baby will be ok but you are right, try to let him know it is not good to be feeling this way right now and try to talk it out and if he gets upset be able to walk away from it until you cool off. so many crazy things happen , so many emotions, dont worry, it is natural and things will be ok. the baby will be ok just try to minimize it in the future. pray for God to help you and be with you in this transitional time. No matter what a great relationship you have, pregnancy can be a crazy time but in the end, it is all worth it and you guys will become closer as you go through this learning experience.
