Multiple records getting inserted

I have a form that is suppose to submit a new record into the database. It does submit the record, however it also submits blank records into the database as well. Sometimes just 1 record and sometimes multiple blank records. Any ideas why that could be? It seems to happen as soon as the page with the Add form is loaded. I don’t even need to click submit
