Gdm pricking post meal pricking range

Can I check post meal pricking range given to me was to try keep within 5.5-6.6, if on n off my dinner post meal was 7.1, is it ok? Do I need to be worried about it? Previously pre-meal pricking supposed 4.4-5.5, but I always get below 4.4 ( 3plus to 4.1, even gt 1 time 2.9). So was told to eat per normal n adjust from there, so I just started eat per normal, last week everything still OK, this week post dinner become 7.1 after eating rice with teriyaki salmon and stir fry long beans and 1 apple. Any advice would be greatly appreciated
