On Wednesday i’ll be 13 weeks pregnant, at 12 weeks i went to my first doctor’s appt and they told me my baby was 15.3cm, measuring head to bottom, all my baby tracking apps plus when i’ve looked up the size he should be they all say est. 7.4 cm. i thought i was 11 weeks going into my appointment but the doctor decided to go by my ultrasound instead of my period, making me 12 weeks. is that big for a baby at almost 13 weeks??
