So Frustrated With My Doc

Last week I found out I have to go for a second ultrasound, I was told when I went for my first ultrasound here that I would only need a second one if there was something wrong with the baby, so of course I got worried. My husband and I went down to the doctor right away to find out what was going on since no one will tell us anything over the phone. The doctor said my baby looked 1.5 weeks smaller than it should be....if that's in weight or length I don't know. The baby is very active in my tummy so I'm not too too worried but still I wonder if my birth weight had anything to do with this ( i was 6 lbs at full term birth while my mom gained 40 pounds during pregnancy) or if it's just because I'm not a huge person to begin with. I don't know and the doc really didn't seem to say what could be the issue. On top of this I was also told I might not have a doctor avail to take me on during the last few months of my pregnancy and that all the other doctors are avail in September ( a month after my due date arg). This is my first pregnancy and no one is telling us anything, we first came to this doc a week after I got back from Syria ( in mid April ) and it makes me wonder why if they knew there was such a back up why in the world did they wait until the end of May to request a Doctor to deliver the baby. I really would prefer not to have a man deliver my baby, it might happen . I was also told to consider a midwife, honestly I know nothing about them, I know of some people who have had a good experience with them but I think I would feel more comfortable with a doctor, at least for my first child.....Canadian health care is declining, things were better for my mom than they are for me, what is going on?????
