Are yellow discharges with an odor, that are released without pleasure or a gush of desire, considered semen necessitating ghusl, especially if they occur before menstruation or when thinking about marriage, bearing in mind that the questioner is unmarried?

"Ignore the whisperings (waswas), and ritual bathing (ghusl) is not obligatory for you unless you are certain that what came out of you is semen, which necessitates ghusl. If you are in doubt about it, then choose, and assign it the ruling you wish. As for yellowish discharge, it is considered menses during the customary period if it is connected to blood; otherwise, it is impure (najis) and necessitates istinja' (washing the private parts) and wudu' (ablution)."
