Anyone had a vaginal swab done?

Hi ladies. So we are ttc baby number 2 and I had a nasty uti last month and have had itchy vagina for 3 months and been treated 3x for a yeast infection but since it won’t go away I have to get a swab test done. I’ve put it off in fear of what it could be and if it can ruin our chances of conceiving… I’m so nervous… anyone been through this? What could it be?

So much going on right now we are remodeling then moving into a new home, ttc in cycle 6, 2.5 year old starts school this week, and hubs works 7 graveyard shifts a week so I’m just fried and don’t need bad news…

Please share any similar experiences and is a swab test like a pap?!
