wondering

Depends on what the soft marker was. Many of them can and do disappear over time; others, not as likely. Short femurs aren't as likely to "catch up", for example, but then again, there can be other reasons for shorter limbs apart from something being wrong, like a history of small stature in your or DH's family = short/smaller baby. Did the peri seem like he/she wanted to follow-up?

I can't really answer the "when" they might do another u/s, only b/c the pgs where I was followed by a peri, I had an u/s at every single appt! Talk about thoroughly scanned kiddos, eek! And weekly NSTs and BPPs for the last 2 months of the pg. Is the peri your primary doc now or are you just seeing them on a consult basis? If it's consult, then I agree with Samantha that they're more likely to take a second look later on, in early 3rd tri, to see where things stand. Otherwise, if you're seeing them for every appt., they may well check back via u/s sooner than that.

Hope all is well and it turns out to be nothing!
