So... I got totally confused. The cycle is 12 and 2 days. The first and second ultrasound were 11 and 5 days. Today's ultrasound was 12 and 6 days. ? The gynecologist says either ovulation has shifted, or it will be large again! Well, I know the exact date of conception and the period should be shorter. How does this happen? I haven't been eating much, I have lost weight and he's growing up! On ultrasound, it spun like crazy, maybe like a senior one would, so probably he'll be big! And how can I not feel him yet? He's spinning around there. It would be nice to feel him already. What schedule should I use as an orientation?
