Hi, Im 21 And I Had My Period Normally The

Hi, Im 21 and I had my period normally the 29th of january. I had sex with my boyfriend the 21th unprotected and the 25th protected. Aprox. 2 days after that i felt itch and yellowish discharge, I went to the Gyn and she gave me Terconazole treatment for 7 days, right now I'm done with my period but I have a white-yellow discharge still (no itch nor pain). What could it be ? I'm worried because I had yeast infections before and none of them had yellowish vaginal discharge and yet she gave me the same medicine she gives me for my yeast infections. (She checked me and said it was fungus like usually, but I think it could be something else since the discharge is different).
