Hi girls! How are you feeling? I'm already 12 weeks today, and I'm only going for the ultrasound on the 16th per the referral. I think I've already done the blood tests and analyses ) I wanted to know if it's normal that I'm having the ultrasound after 12 weeks, almost at 13 weeks. By the obstetric dating I'm 12 weeks but by the first ultrasound I'm still 11 weeks.
