Coming off the pill & pH change?

I have been on the combo pill now for 3 years. I decided to come off of it due to having so many pill-related symptoms. Since coming off, I have felt so much better. One thing I’ve noticed is that my vaginal discharge has a very different smell. TMI - not fishy, but more acidic. Is this normal? How do I fix this? I bought boric acid suppositories and used those for about 5 nights, but the smell came back. I also have been taking women’s probiotics daily.
