Hi Zoecat,
welcome to Moomie and congratulations on your pregnancy.
Sounds like a horrible experience, but don't worry too much, the best scans are yet to come (the ones where you can see an actual baby rather than a blob)
Trust your instincts and if you have to meet with a couple of Dr's until you meet the right one, then so be it. Remember that you are paying for a service and that the Gynae is not doing you a favour.
I liked my Gynae at first but as time went on he did not seem to want to support my birth choices and wishes and so I ended up changing Dr's two days before my little girl was born - it was the best thing I ever did .
I wish I had changed Dr's in the beginning when I had a nagging feeling about my first Dr. it would have saved me a lot of stress.
Don't expect Lengthy visits though with any Gynae's , the norm is about 15 - 20 minutes. That's why next time I am going to consider the Midwife approach , I have heard they really take their time
Good luck finding the right Gynae !
