I've been there, twice.
Yes as the pregnancy develops more insulin is needed for you and baby. Higher bgs give fatter babies and a nightmare to deliver naturally. I had 2 natural births on insulin. The hospital just need those numbers in the good levels for baby health and yours for strength to push baby out. Without any strokes or internal damage. Baby scans are just a guide not 100% accurate. My babies were 6lb 4oz and 8lb ½oz. Smaller baby came 5wks early. I was relieved as he stopped moving at one stage but I got checked and my bgs were too tight but that improved. I was relieved last baby was out though as my confidence in one of the nurses had gone. She wasn't great at her job. So I did what I did for first pregnancy and it was a success.
We are looking to them for support but in the end I listen to consultants and baby and i were great.
So will you and bump will be too.
I filled in a diary and it got me through any odd readings and too tight readings too. I feel I ate less in 2nd pregnancy but finances where so different from 1st pregnancy to 2nd one.
I used my diary every few hours and filled it in but the difference I made to what I do now is I don't look too far on past bgs. I only concerned myself with todays and some of yesterday's results on my meter. Also tried to envisage what I'd need at my next insulin jab. Hospital concerned themselves on basal more and I took their advice but individual insulin jabs were my main concentration.
Are you using a paper diary????
Keep it close and use it all the time. Just til baby shows an appearance. Then maybe no more strict monitoring. Some no longer hv to but myself I always test. It tells me how my diabetes is coping with my busy life.
Its not a bad practice as in the future you may need to monitor heavily again.
