You and your son might have thrush, a fungus infection caused by Candida. Vaginal thrush could make you feel itchy and produce a discharge that looks like cheese. Typically, you’ll be advised to use antifungal creams or tablets. Treatment for oral thrush in your son can involve antifungal oral gel or drops.

Commonly, a contraceptive called plan B can lead to some irregularity with your monthly cycle. A delayed period can be your pill or stress because you are scared of getting pregnant.

Your period's regularity could result from anxiety, hormonal shifts, or perhaps pre­gnancy. Signs might include abdominal bloating, me­nstrual-like cramps, and tender bre­asts. It's wise to be patient, se­e if menstruation begins. If it doe­sn't, consider getting a pregnancy test for de­finitive confirmation.
