A Stomach Virus Swept Through My House Recently, I Got

A stomach virus swept through my house recently, I got it in addition to my husband & children. My children had light vomiting, followed by diahrrea & high fever. I only had extreme vomiting no diahrrea. I recovered from the stomach bug but I haven't had a bowel movement since getting sick. It has been seven days and it's painful. I have tried everything. I have taken a probiotic everyday. I eat healthy. I have been hydrating. I tried milk of magnesia and even an enema to no avail. I am miserable. What should I do?
