YANBU, I had a really horrid experience during my booking in appointment. Its my first baby and so this was the first time i'd ever been in contact with a midwife. She showed no warmth, no empathy, was very negative, she showed no basic level of care (I have never known anyone take a blood sample in this way!) and basically if you haven't got the picture by now, her attitude stinked!!
I was left feeling judged and upset, I felt that had I have been a 'Mrs' or had my partner been present or if I had managed to get out of my trackies and put some makeup on, then maybe she would have treated me differently. She treated me like I was second class.
I too am an independent, confident, positive person and I rarely 'let the bastards get me down' but she succeeded good and proper!
Anyway, all the midwives I have seen since then have been as I expected a midwife should be. And so far fingers crossed I have not had to cross paths with the horrid one again.
So I think unfortunately you probably just got a 'bad one'. Think back to your other appointments with other midwives, you probably would have left feeling totally different had you have seen one you were happy with previously?
Like the other posts have said what she said to you is probably her job to say it, but IMO how its said it just as important.
I wish you all the best, and although i'm sure you will find it incredibly hard work, i'm sure you will do a great job. Good luck !
