"The only side affect I received from this BC is hypoglycemia. This started happening a couple of weeks after taking it. At first it would happen after I went running, but then it started happening randomly/ without working out. And it was a SUDDENLY drop so there wasn&#039;t a way to prevent it. Once I thought about what changed and narrowed it down to when I started my BCs, I stopped taking them immediately (1 yr later). After ~4 days I went running and didn&#039;t experience hypoglycemia at all. From that point on I was hypoglycemic free. I don&#039;t think anyone knows about this side affect which is unfortunate. Just some background: I was 34, am a black female, and wasn&#039;t on any other medication."
