Lower abdominal pain after second glucose test

Failed my first glucose test and went in today after fasting for 12hrs for it and experienced nausea and weakness after the first blood draw pressure drink. After drinking the 750g orange drink I started to feel discomfort and slight abdominal pain maybe 10min later. Its lasted just over an hr, I only notice if I get up and walk around. Is this something to he concerned about? The lab tech said it's likely from the sugar in the drink but it was just similar to how I felt healing from my ectopic last year so just doesn't seem normal to me. Anyone been in this situation before? Currently 26 weeks and 3days
