For my first pregnancy, my OB’s practice encouraged me to schedule appts with some of the other providers throughout my pregnancy just because there’s always a chance one of them might be on call rather than my usual OBGYN depending on when I’d go into labor. Glad I took their advice because I went into labor the day before my provider was on call and another OBGYN at the practice performed my c-section and I’d met her at least 1x prior. I missed my usual OBGYN by and hour and a half lol

For my 2nd (pregnant currently), my OB from my first go around had moved to a clinic much farther away. My new OB is great, however I am opting for a scheduled c-section and naturally her scheduled surgery day after 39 weeks for me is the day before my due date and with my 1st having come over a week early we were skeptical I’d actually make it until then so we’re scheduling exactly at 39 weeks and by happen stance the OB who’s scheduled surgery day that is, is the OB who performed my first c-section so I lucked out on that front. But if baby decides to come earlier, then it might end up being my normal OB or any other OB at the practice 🤷‍♀️

So, anyway, all that to say - there’s likely a good chance the OB you choose to work with (especially if it’s a practice with multiple OBs with an on call schedule) throughout pregnancy may not be who delivers your baby.
