I haven't heard my twins heartbeat since I was 6 weeks so I've been always wondering if they both were still there and ok. Had my 12 week checkup today and they found both right away on the doppler. 162bpm and 158bpm. She said they were both moving and all was well. :) so happy. Now to schedule my peakaboo ultrasound for 15 weeks so I can get another look at these two!
