I hadnt hired a midwife, but I did consult with two later in my pregnancy when we werent sure dh was going to be able to make it home for the birth. So while I didnt have to terminate, I did have ot make the awkward (for me, I'm awful at anything even resembling confrontation) call letting each of them know I was going to go uc after all. The one I just left a message and didnt hear back after that, although I know she was supportive of my choice. The other was really so amazing, calling to make sure I was really comfortable going uc (rather than just couldnt afford her) and she offered her availibility last minute without a contract or via phone if we had any questions or concerns during/after. Good luck, I hope your mw is receptive/respectful.
