Why can’t my sims in the sims 3 tar pregnancy test after trying for baby?

@Bookworm0023  Are you playing Sims 3 or 4?  There are no pregnancy tests in Sims 3.  If you don't hear the baby chimes, one way to see whether your sim is pregnant is to click on the ground and select "Go here."  If she's pregnant, she'll get a square command in her action queue, rather than the usual longer one with various options (automatic, walk here, run here).  This is only applicable if she's standing on solid ground.
