Baby head first???

Shonise • I'm 25 years old. I have a 3yr old daughter and a 9yr old son. I'm happily engaged as well! Nd now pregnant with my 3rd!
Tues morning at my appt my Ob measure my stomach and check his heartbeat. I was 27 weeks...now I'm 28 weeks..He's definitely growing but I ask her where he was when she did the heartbeat he was head down will he possibly move around some more then go bk to the head down position when its time???? Cause this pressure I'm feeling ain't cute!! Lol
