Basal injection time

Good morning,
I am pregnant with DG, I put myself at night Insulatard, I started with 6 but now I have had to go up but I can't regulate it, I'm going for 10u.I usually inject the at 21.45 at night, and I get up at 7:30.If the insulin injected me later about 23-23.30 will it influence something?It has nothing to do with?Or is I still increasing units?
Thank you

It will not influence anything as long as you do not use other insulins.Remember, insulin Humalog Mix (and mixtards) are a combination of two insulins;Insulatard is a single type of insulin.
