Pre term Labor test

at my 31 week check up I mentioned to my midwife about having contractions that day. She did a fetal fibronectin test that came back positive so now I am on bedrest for 2 weeks til we can repeat the test. Anyone else have any experience with this?

Re: Pre term Labor test

  • Did you have sex the day or two before the test? I've had it done a few times (both negative) but it sounds like false positives are common, especially if you've had sex or a cervical exam 24-48 hours before the test. Hope in your case it's a false positive!

  • I have had ffn done twice. both times was negative. it's notoriously unreliable, unfortunately. but i think your midwife is still recommending best course of action! good luck! Sorry you're on bedrest- it's so boring! but hopefully your peanut will stay put for a while!
  • No sex or exam before the test ( about a week since sex) but I'm hoping for a false positive! It is boring! But with 3 other children never a dull moment! Thanks!
  • I had a Ffn come back positive a few weeks ago and I have not gone into labor yet. But it has been a little nerve-wracking.
  • Hopefully we both make it awhile longer! :)
  • I just had the FFN a couple days ago bc I was having contractions every 3 mins while hooked up to the monitor. A negative result is 95+% accurate at telling you that you won't go into labor in the next two weeks. But, a positive result is only 20% accurate at predicting labor in the next two weeks. So it's a good test for reassuring that you won't, but not accurate at predicting that you will.

  • I had a 2 hr contraction "episode" this morning. They got so bad I had to get in a warm bath, which eventually slowed them down and they finally stopped! I was in tears for a while there. I'm going to have the dr check me tomorrow to see if these "episodes" are doing anything. :(

    This test isn't very accurate if it's positive, but extremely accurate if it's negative. In midwifery school, it was the actual example we were given to understand specificity and sensitivity.
  • Let us know what doc says about those contraction episodes!!! I have been having them since 24 weeks, but just about 2 weeks ago they started causing some change. Just effaced 50%, no dilation, doctor only grimaced but said no restrictions, just take it easy.Fine wtih that! Hoping good things for you!
  • I will update after my appointment. Thanks everyone!!
  • At my appointment my midwife decided not to do any checks or anything to mess with my cervix so nothing gets started. I get it but my anxiety level is through the roof. Oh well, keeping this baby girl safe is top priority!
  • ahhh! I'd be goin nuts! But she does have a really valid point. ahh! crap situation. Sorry :/
  • Thanks, no contractions for almost 48 hours! The longer that goes the better I feel! Thanks for all the advise! :)
