Im 16 years old, and sexually active. Im on birth control, and i probably have sex about three times a week or more. My mom knows about it, and she helps me with stuff, but something were both concerned about is why i keep getting UTIs. Ive been trying to pee before and after sex, which i think is helping..what can i do to prevent getting more in the future, because its a hassle going to the doctor so often. Also..my lower abdomen sometimes hurts after sex, like close to where my ovaries are. Is this normal?
