Is it good that after applying clotrimazolum revaginal tablet for the night, in the morning I have cottage cheese secretions on my underwear?

Good morning, after the first use of clotrimazolumva tablets I have secretions like cottage cheese. Before the visit, I only noticed at home more creamy secretions, and less secretions sticky, white with lumps. I was also tired of sewing, stinging in the sheath and itching the vulva. Is it good that after one tablet in the morning i appeared on my underwear this cottage cheese discharge? Also in 5 days I will have menstruation. Should I take these tablets twice a day for 3 days?
