RhoGAM shot

Sierra • Wife 💍 And mom to a baby girl 💘

I’m RH- and my husband is RH+ so ive been reading on the RhoGAM shot and I’ve seen scary things. Is there anyone who’s waited to get the shot till after birth to see what their babies blood type is? I know you can go up to 72 hrs before it’s too late after birth. (Sorry if this is in the wrong group I don’t know where to post this)
