Go get a 4D ultrasound. Their kinda expensive but if you really want to see your baby that would be the best way. I was told to do it between 28 and 32 weeks
I didn't get an ultrasound after my 20 week one. They only give you one if there's a problem or you go a week past due, so you don't really want to need another one. Trust me, it's worth the wait until you get to see and hold your baby.
