I can't remember when I got it with my first born but i'm already just hitting 29 weeks and my next doctors appointment isn't until the 29th. Everyone I talk to and what I google it's around 28 weeks. I told my doctor in the very beginning that i'm going to need the shot, and a few visits ago as well. Just hoping it didn't leak through the cracks or something. Is it normal to wait till around 31 weeks to get the shot or should I call my doctor and set up a separate appointment? I think either way i'll call them tomorrow but just trying to ease my mind a little tonight I guess.
