I have my 25 week midwife appointment in a couple weeks. Is there anything special that's going to happen? My OH didn't come to the 16 week one as we thought it was just a check up and he missed hearing the heartbeat (though I recorded it). Do they do another heartbeat check? Or anything else? Or is it just a general check up? Thanks!
