I would like to ask, my last appt at 20 weeks the doc said i will need to go for the glucose test. I also received the lab form by the psa. However, i have yet to receive the date when to go. KK send me sms on two dates, 1 for just doc visit & the other for location of placenta. Im lost, i called & asked when should i be going for glucose test, the helpline said they are not sure. oh no, what should I do?
