Refused glucose test 🤨

I couldn't do it. They only had the lime one and the lady was being rude. It was thick and hot I just couldn't do it. I told her I did not want to do the test. It made my head hurt and in 3 mins I still had over half of the drink left. SMH FML. Do you guys think it will make a big difference if I don't do it? I'm 31 weeks BTW.
