When Su Xixi's initial shock was over, she looked at Xiu strangely and asked, "How far along are you?" Xiu held up her hand showing her five fingers. "Five weeks?" questioned Su Xixi.
Xiu looked at Xin Zimen, "Ah-Xin, add a finger." Xin Zimen rolled his eyes at her but still held up a finger to make it 6 as she added, "It's 6 weeks almost."
Su Xixi looked at their teamwork for a moment in a daze before pointing out, "Isn't it too early to tell the gender? The embryo is barely about 4-5mm long at this stage. A very basic beating heart and the circulatory system develop during this week. You really can't figure out the gender."
"Are you a doctor?" asked Xiu.
Su Xixi shook her head, "No, but I also gave birth to a daughter." She took a pause before adding, "That's why I know that the earliest you can find the gender of the baby is around week 14 and mostly that's not very accurate. That's why doctors schedule an ultrasound at week 18 to week 21."
