New to birth control!

Sheena

I just started using a generic brand of birth control. I started it on the first day of my period (to minimize the side effects) and I’ve noticed a change in the colour and smell of my discharge. My discharge is brown, I assume it’s just from a little bit of breakthrough bleeding. But my discharge smells a little vinegary/acidic. I wasn’t sure if this was normal. And I was also curious if these symptoms will go away
