Theresa (Jen Lilley) was genuinely excited that she was pregnant with Brady's (Eric Martsolf) baby, but her joy could be extremely short-lived on Days of Our Lives.

Theresa Confesses Her Pregnancy News

Though Brady did learn the truth about her putting John (Drake Hogestyn) into a coma, which made him want nothing to do with her, the news that she was pregnant with his child was enough to convince her that she wouldn't suffer any consequences for her actions, and would eventually be able to get her happily ever after. But all of her plans will be shattered now that Kristen (Eileen Davidson) has learned her secret-and is plotting against her.

Kristen's initial motivation for coming back to Salem was to get pregnant with Brady's baby, something she was unsuccessful at accomplishing-and now she plans to leave town again for good following Brady officially telling her he was through with her after catching her in bed with Daniel (Shawn Christian). But after hearing Theresa's secret, she will scheme to get exactly what she came to Salem for-putting Theresa in great danger.

Brady Makes A Shocking Discovery

After Theresa leaves the pub with Anne (Meredith Scott Lynn), she will encounter one of Kristen's thugs in the park-and before the altercation is over, she will be unconscious and will be brought to Kristen for the biggest scheme the DiMera daughter has pulled yet-removing the embryo from Theresa and having it implanted in herself-effectively allowing her to kidnap Brady's child and keeping it all for herself.

Days of Our Lives airs Monday-Friday at 1 p.m. on NBC.
