"Long waiting time and different things told by different professionals"

I had my antenatal appointment at 1.30pm at the clinic. I arrived on time, sat and waited for over an hour. I asked the receptionist (where I never see them smile or friendliness for some reason), they told me to ask one of the midwives, so I stood and waited to ask one of the midwives. 

So the midwife I asked said my pregnancy book has been taken by a midwife and I should be called in a few seconds. Nothing I can do. I waited with full bladder cause I was too scared to miss out. Another half an hour later I was finally called. That was around 3pm. Having mild depression I was very anxious, worried about getting fined for the parking tickets I bought for 1.5 hours only, worry about my child waiting for long in daycare for me to pick them up etc. 

After a few minutes of seeing the midwife, I was asked to wait to see the diabetes educator. So another hour of waiting. I was the second last pregnant mum in the area when I got called. What puzzled me is, many other mums who came after me (which I know there are 2.30pm appointments as well) had already left. I left at 4.30pm. 

I put a lot of emphasis on punctuality. I understand they are busy but I do not expect myself to be feeling happy seeing myself arrived early and treated much later than anyone else. I do not see how the system works, there is no point in booking my appointment earlier. 

--second story--

As I was on insulin, my last 2 visits (4 weeks) I consulted one of the doctors in the diabetes clinic. I asked if it is ok to increase my fast acting insulin when I dine out so I have more food options for myself. They said that's what insulin patients are doing so that is totally fine to do. 

After 4 weeks of doing so (occasionally when I dined out I put up my insulin), the consultation with the diabetes educator recently was shocked I did that. I couldn't remember the doctor's name (after seeing different professionals each time it is hard) but I clearly got their 'approval' to do so. The diabetes educator was telling me the worst scenario of doing so is that my baby may not be adjusting well with it when they are born, potentially may lead to brain damage etc. My heart just torn apart. They are telling me different things, I feel devastated and do not know who should I listen to. Then I left, crying all the way home.
