Another one here in a similar position - also planning to start trying in a few months, but like you am nervous of going ahead because of fears that buried memories will be stirred up and I won't be able to cope. We have been putting off starting a family for the last 4 years because of my fears.
I entirely empathise with your worries about medical professionals judging you if you disclose your concerns, but if it helps at all, I disclosed mine and so far have found my GP unfazed and very supportive. In fact, she was the one who suggested an EC as something to consider (I didn't raise it - she did) and she offered to support me in whatever I felt was the best way forward and to refer me to a sympathetic consultant if my choice was the EC route. We've moved house and had to change GPs, I have only tentatively broached the subject but so far, found the new GP practical and supportive. I haven't discussed with any other medical professionals yet as we haven't got that far.
There are, sadly, an awful lot of women out there who have memories in their past of things which should not have happened and will have similar fears as a result. So while not exactly a "routine" daily occurence (thank goodness), chances are that your GP and midwife will have heard similar fears before and should not mistake what's driving them. This fear and distress - so I'm told - is normal for someone with your history. It absolutely does not reflect on you or your ability to be a mother.
On the other hand, I've also read somewhere that 60% (or some high figure like that) of midwives in a survey said they weren't confident they would know how to support someone who disclosed a history of past abuse. I don't take this as meaning they would be judgmental in the way you fear - but I guess it does mean that some people may be clumsy, or not know the best way to help.
A book which has been recommended to me, and has some good reviews - though I haven't read it yet - is "When Survivors Give Birth" by Penny Simkin. www.amazon.com/When-Survivors-Give-Birth-Understanding/dp/1594040222
Barkfox, I hope your meeting with the consultant midwife goes well. I would really like to know what happens if you are willing/able to say. Appreciate your desire for privacy (as you can see I've changed my name for this post!), not sure how messaging works here though...
