@eira Hello, It is not uncommon to have this reaction to hormonal changes that occur with your cycle. However, douches, topical sprays, etc. are not recommended. They can disturb the natural balance that keeps infection down. Yeast infection after the period is due to High levels of estrogen causing Candida fungi to overgrow. Because of this, it's common to get a yeast infection around the time of your period. Some people get yeast infections around the same time of their cycle every month, a condition called cyclic vulvovaginitis. You may try eating yogurt every day - the kind with active cultures. Some women find it helps. Wear only cotton underwear and avoid perfumes, bath oils, etc. Also, discuss this with your doctor. Thanks!
