Advice please gestational diabetes

Hello so just found out I have this, and gave me a reader to prick my finger and check my levels till Monday. But my readings are coming back high, yesterday they was in the 6.4- 7.8 1 hour before I ate a meal and today it’s 8.9 1 hour after I’ve eaten a breakfast meal which was 2 whole meal toast and poached egg? She is meant to ring Monday to go over my results to see if I need medication but that’s seems along time to go with these results? So should I ring or wait till Monday? I’m unsure?!
