I want to know so bad!

My first instinct is yes, pregnancy can have unexplained effects on a household. It could also just be a virus, sometimes children are more "clingy" when they don't feel good. But you know whether or not that is the case with your child. If you take a test and find out you're not pregnant and your husband and sons symptoms don't go away on their own; you may want to ask your clergyman to come pray a prayer of cleansing and protection for your home. If you feel uncomfortable doing that, you can do it yourself. Sprinkle salt (this focuses your mind and "marks your territory" ) around each room and the outside of your home. As you do, say a short prayer and demand that any unhealthy entity leave and ask the Lord Jesus Christ and the Holy Spirit (if you are Christian) to enter, cleanse, and protect your home and family. Good Luck!
