I think I have a yeast infection. . . . My period ended a day or two ago, and now there is some residual blood-like discharge mixed with what looks like cottage cheese. The blood is only apparent when I wipe after using the bathroom. Is it possible this was caused by wearing a sanitary napkin for too long? I wasn’t feeling well and slept for about 12 hours without changing my pad. Is it normal that this would occur in conjunction with my period? And is the only way to treat this with over the counter creams?
