You have a yeast (thrush) infection. You often get them after antibiotics but stress and hormones can cause it too. It's caused by an overgrowth of the naturally occurring Candida albicans yeast found in your body.
Treatment involves getting an over the counter anti fungal from the pharmacy. You can use a cream or pessary ie clotrimazole (Canesten) or take a single dose tablet ie fluconazole (Diflucan). At the same time you might want to take some probiotics to help recolonise the good bacteria in your gut.
