Even though I was hesitant to make suggestions to my doctor, I was brave and emailed her regarding the fetal fibronectin test to see if it would be helpful in my situation. Here is her response:
Fetal fibronectin is a test that can sometimes help us know if someone is going into preterm labor. It doesn’t really help us with shortened cervical length to predict what will happen. It’s most often used when someone comes in with preterm contractions and we’re trying to distinguish preterm labor contractions vs. “Braxton hicks” preterm contractions. And its most useful when it’s negative – to say that someone is not in preterm labor; however, if it’s positive it is not predictive of preterm labor (that’s kind of confusing – I hope that made sense).
So I do not see this test in my future. One thing on my list ruled out 🙂
