Hello and welcome to HCM.
Thank you for your query.
Although vaginal discharge
is listed as one of the side effects of birth control, it is also a sign of an infection. Which is why you might have to report to your doctor to get examined, and rule out/diagnose an infection. A few of the other more common symptoms associated with an infection are:
-Burning sensation while urinating
-Increased urge to urinate, but less amount of urine passed
-Lower abdominal and/or flank region pain
-Itching around the genitals
-Blood in urine or immediately after (not always seen)
-Painful sexual intercourse
and a few others.
