First Ultrasound

Had my first ultrasound today at 6w1d, baby is measuring 6w2d. Tentative due date is 11-27-17. Heart rate was 113 BPM ❤ we lost our last baby in October, baby measured 7w4d so while I'm beyond thankful for what I saw and heard today I can't help but feel like I'm not in a safe zone just yet.
