Could I get my uti back by being fingered after 2 or 3 days since I last took my antibiotics macrobid

I know this is too much info. No judgment please. I finished my antibiotics 2 or 3 days ago. Idk how long antibiotics for a uti stayed in my system but my partner fingered me today. I’am wondering because of pushing so deep... will that push bacteria back in that’s suppose to be coming from this antibiotic? TIA
