Pills and depo shot

I used to be on the depo shot but heard it’s hard to get pregnant when off of it and trying so o switched to the pills. Ever since o switched to the pills I have many bacterial infections and yeast infections it’s awful. Can the pills cause this? Should I just stop taking the pills until my doctor appt Monday? Will I have crazy hormones if I just stop taking the pills? Thinking of switching back to depo on Monday.
