My experience last pregnancy and this time is the same as Angie's. We did a viability scan at 6 weeks then another at 8 weeks (after that point the Doppler picked up h/b). I had the first trimester screening u/s at 13 weeks, then an anatomy scan at 18 weeks. From that point, we've done growth scans every four weeks (every other visit). Around 32 weeks, we'll start weekly BPPs, too, and continue with the growth scans.
