I just got a call from the Dr. today, I have my follow up ultrasound Monday morning. I had one last friday when I thought I was 4+6 and they saw a gestational sac which measured at 5+2. They saw 1 sac but couldn't see a heartbeat yet or much in the sac so I am going back Monday. I will be 6+5 based on the ultrasound due date, or 6+3 based on my LMP. Hoping we see a heartbeat this time! I'll update right after the appointment. I'm super hopeful and excited!
