It's the usual story, everyone is different.
With my son, all went quite smoothly till about 6 weeks before he was due. The only problem was that I wasn't putting on enough weight, so was told to increase my carbs. About 6 weeks before he was due, on a ward visit to maternity hospital, my BP was high. Half an hour later it was normal (very hot day, bumpy ride on bus and walk uphill to hospital) so not unexpected. Consultant said I could go home but wanted me as in patient the following week. Every time BP was taken for next 5 weeks, I was told it was fine. I was induced at 39 weeks +2. Baby was 8lb 2oz and needed treatment for jaundice a few days after birth.
With my daughter, my BGs were dreadful - unexpected highs and lows all over the place. I was induced one day after her expected date and she was fine at 8lb 3oz. My BG didn't get back to normal, even when I stopped breast feeding. The diabetic clinic seemed to ignore my worries about this for decades, but I think my coeliac disease started during my 2nd pregnancy and wasn't discovered till my daughter was 27!
I often wondered if coeliac and diabetes are linked!
When I went low carb my Bgl leveled out and became normal, however when I had a "treat" I became really bloated and felt really ill. I asked if I was intolerant to carbs and if that is what caused my diabetes... she said no, but it sounded like I had coeliac... they were going to do tests but never did.
I often thought that they just say no because nobody has looked into whether diabetes is caused as a by product of another illness that went unnoticed.
It would answer a lot of questions such as why not all diabetics are fat and unhealthy.
I was told I would develop diabetes because I had gd really badly and needed insulin... I think it was actually down to the hospital and the care I received.
I have changed hospitals now and receive excellent care. When diagnosed with gd or become pregnant while diabetic, the first step is that woman attend a group meeting to show what we can and can't eat, including understanding the labels. They follow and teach 'low carb healthy fat diet' though higher carb than me... it was the dietitian who manages your diabetes at first until you click, and then hand over to the diabetes midwives. You get her number too so that you can call whenever to get advice.
My last hospital just told me I was eating too much and cut down which puts a shed load of pressure (and all the blame) on you... I ended up so depressed and starving hungry while watching my Bgl rise!
I burst out crying in the group (possibly hormones) when the dietitian said... "if you need to go on meds it isn't your fault, don't starve yourself to try to control Bgl."
Having the right help and care and info is really important. What works for one might not work for some!
