Protein per lb during cut

Im female, 5' 4", 128lbs and 7 weeks out from my first bikini show. I have chosen not to get a coach for this prep and seem to be making good progress over the last 10 weeks! My question is about how much protein is "okay" to eat. I have a minimum of 150g a day, but normally eat closer to 170-180 (ends up being about 1.5g per lb). I am wondering if this is too much protein, and if it will effect my weight loss negatively? I am continuing to lift heavy. I only am eating that much because otherwise I am starving all day! Macros look like this...
LOW DAYS
Carb: 125g
Fat: 53g
Protein: 150g minimum
HIGH DAYS
Carb: 180g
Fat: 45g
Protein: 150g minimum

Thanks!
