Feeling blue

Today has been too many emotions. My husband is a good man. We've been completely inseperateable and so in tune. These past couple of days have been so different. I feel like we're just on different pages. I don't like it. A lot has been happening like moving into my in laws house for a week until our new place is ready. Job stress, our business and new employees. I just feel lonely and want to cry. I feel like I take it out on him at times. We've been enjoying the pregnancy and now I just feel different. Is this pregnancy blues?
