Can a mouth swab dna paternity test show that im pregnant?

Q: I did a mouth swab test today for court regarding my 17 month old and his father. His father said I look pregnant and that if I am he will get full custody. If I am pregnant would that show from a mouth swab? I would think not other wise pregnancy test would be mouth swabs right?
and even if it could detect that… They wouldnt be able to disclose that info without my say so right?

A: No, you can’t tell you’re pregnant from a DNA mouth swab. The pregnancy hormone is only in your blood or urine, and you need specific chemicals to interact with it to show a positive pregnancy. So unless you’re specifically looking for it using a blood or urine test, you can’t tell.
