agnesyp, if your pant is too short, you can try to 換碼. i remember when I bought last time in kln city 樓梯口間shop, the lady said if size is not okay then can change anytime. Not sure which shop you bought from for the 大肚褲 nei

其賁睇你自己想唔想, 因為政府唔一定幫你做.c+ doctor 就通常會幫你約時間做. 好處係結構性u/s主力睇BB既身體構造, 內臟/四肢/ 有無兔唇咁.. 買個安心都好. 我唔係政府覆診, 所以我私家doctor 會幫我約係20 weeks 做. hope this information is useful for you.
