Its not really that scary.. well I didnt think it was. I did my glucose test during a routine appt with midwife. I went in, drnk the sugary drink which i thought was like very sweet lemonade, and then my midwife did all the usual things for the appointment - BP, listened to bub on the doppler etc. Then I went out into the waiting area and read a trashy magazine until the hour was up, and then I went into the room next door where they took some blood. I didnt need to fast in the morning before the test, but I obviously couldnt eat aanything during the hour. All they told me was to eat my usual breakfst but try to not have anything overly sweet before the test. I did feel a bit yuk while I was drinking the sweet drink and for a couple of minutes afterwards, but I wasnt sick.
