Ok late, deep breath. You need to be calm today, so remember to breathe. As soon as you get there, and they run through the procedure you’ll know. They wont do anything you don’t want them to do, so bear that in mind and go in armed with your questions. If its booked without then sounds like you’re having it without, as wouldn’t it take longer with and be an entirely different procedure, ie you’d need an anaesthesiologist wouldn’t you like during an EC?
What’s the worst that can happen, take to your Dr about that scenario, and dispel the fear. Xxxx. Best of luck, but remember to breathe.
