Anterior placenta

I found out at appointment today that I have an anterior placenta (I think that's what it's called lol. Placenta in front. She said that's why I don't feel my boy as much right now. I'm 21 weeks today. She said at 23 weeks I should feel him 6 times an hour and if not I should go in to get checked. I'm not to worried about the placenta thing as I read it's common but am worried about not feeling him when I should. Has anyone else had this and felt their baby regularly by 23 weeks?
