I am still new so many of you girls don't know me or my situation. But I'm 29 weeks pregnant,my child's father is going away so Will miss the birth,and I've been under a lot of stress this entire pregnancy. This morning him and I got into a big argument between stress lack of sleep and my In laws dog peeing all over the house so I've been cleaning since 6am we both just snapped and started arguing. My stomach is now cramping and feeling very "heavy" when I walk is the best way to describe it. Any advice and do you think this should be a call to my Dr or just from the stress? Thanks girls
