Positive FFN ( fibronectin

so I’m high risk with a cerclage and did my usual FFN (Fetal fribonectin) swab on Friday got my results today and it was positive. Did any of you really had that experience previously where u gave birth two weeks following a positive test or was it longer. My doctor prescribes steroid shots, I took one dose today and have another one tomorrow but I cannot stop stressing, I’m 30and 5 days and I just want to know if any of you had the same experience and what happened. Thanks in advance 🤗
