Feeling like she's about to fall out!

Hi everyone. I'm going to address this issue with my OB on Monday but was curious if anyone else is having this issue.

Im 22 weeks exactly & feel like she's sitting so low in my belly. So low that when I get up and down it hurts like she's gonna just come right out. In my last ultrasound the tech said her head was face down right in my pelvis.

I'm just a little concerned because i went into labor with my son at 31 weeks. I am trying so hard to make sure I dont go prematurely this time as well.

Thanks in advance for any advice and stories ladies!
