Talk to Gynecologist on Canesten Applicator

hi. age 28 . married. 8 months pregnanat.

i have vaginal infection like thick curdy discharge. i purchase 6 canesten at one time and there is only 1 applictor. so want to ask should i use this one applicator again and again for all 6 tablets or should i purchase new one for each tablet? because i think its hard to purchase only applicator indiviually every time bcz applicator comes only with tablet..
