I am 13 weeks pregnant and just had an argument with my husband that involved shouting at one another (the first argument we have had since pregnant). Almost right after things simmered down, I began to feel slight cramping in my lower right side around to my back. It lasted about an hour and has now calmed down and I'm wondering if it's from the stress of arguing, normal for my weeks, or something has possibly happened to the baby? I was also moving things around the house today just before the argument broke out.
