D&C question

Ok I just had a D&C; and doctor gave me just one dose of antibiotics which was doxycycline to prevent infection but after I remembered that I had felt a bit itchy down there before the procedure the doctor said based on what he saw he doesn't think I have a yeast infection but he still prescribed antibiotics for it and for that he prescribed fluconazole

Is it bad if I take the antibiotics even If i possibly don't even have a yeast infection? Or should I just not take them

I think the nurse said (and I say I think cause I was kinda out of it from the relaxing medicine they gave me ) but I think she said the antibiotics could also help to prevent a yeast infection since the antibiotic they first gave me could cause a yeast infection

I hope this makes sense

**also if anyone knows since I already took an Antibiotic after the procedure

Can I take the ones they prescribed also today or should I wait till tomorrow?
