Is it possible for STIs to persist for 10+ years in a monogamous relationship?

Just wondering if it's possible for STIs to persist for 12+ years in a monogamous relationship? My husband and I never got tested before we met and we each had a handful of previous sexual partners. We were very young and it just never occurred to us to check. I have no reason to think we ever had anything, though we did experience the odd yeast infection, epididymitis, and a UTI.
I know I  was tested for HIV, hepatitis b and syphilis before each of my two pregnancies so I'm just wondering if anything else could have gone unnoticed? I am very health-conscious now and in particular worry about having passed anything on during childbirth.

It's also likely that during your pregnancies, you were tested for gonorrhea and chlamydia, though that's not as standard as it should be.

However, if you had passed an STD to your child during birth, your baby would have been very ill. Gonorrhea and chlamydia can infected a newborn's eyes, give them pneumonia, among other things. If you have herpes, the only dangers would be if you were infected during the third trimester or had an outbreak during birth - both of which you'd know by now.

A baby born with an STD isn't something you or your doctors would miss. You can stop worrying. :)
