…Can having a hernia cause the stomach to be enlarged?

A hernia should not change the results of a pregnancy test. If you have a concern about a hernia, you should see your general physician for an evaluation. There are abdominal masses and conditions that could cause enlargement and bloating, so it’s best to talk to a professional. You may want to run an at home pregnancy test if you have had unprotected intercourse and are worried about pregnancy.
