Chody, I don't think I had low Papp-a but my placenta is calcifying early, and bubs growth has been restricted. I've been having weekly scans since 32 weeks, just to check on bub, and fortnightly growth scans. I had the steroid shots at 32 weeks as well just in case early delivery was needed. Last Monday we had a growth scan and bub had virtually stopped growing, very minimal growth and has dropped off the percentile chart for abdominal circumference. We are around 15-20th percentile for head circ and biparietal diameter which doc said is fine, but not when abdomen has stopped growing. Baby's estimated weight was 5lb 3oz, after only gaining 250g in the fortnight from last scan. Weights by ultrasound can be way off though. It just sounds like we were going to have a petite baby anyway if all else had gone well.

After those results, dr decided that baby will be born by caesarean tomorrow (baby is frank breech, IUGR, low amniotic fluid and increased umbilical dopplers and technically pre term by one day!), which is 36+6. We have been having CTGs 2-3 times a week as well and baby has still been very active and happy, so I think that has helped the argument for keeping baby in as long as possible.

Ask lots of questions at your appointments, set your mind at ease! The only thing I have found online about this is that every situation truly is unique, my best advice is ask for reassurance if you need it, even if you feel like a nuisance or like you're over reacting, it's no worry to them to give you extra monitoring-better safe than sorry! And my dr told me that one of the most important things was my perception of the baby's movements, if anything changed or there was a decrease I had to report it straight away and go in to L&D. He said their tests are only so good, and if baby gets distressed it will stop moving.

That's just my experience, which will likely be different in the long run to yours, but like others have said, you're still on the charts, which is great news! All the best with it, I'll be interested to see how your next growth scan goes (another thing dr told me-a single growth scan doesn't tell them a whole lot, they need more than one to compare data to make sure baby is still growing).
