Could possibly deliver today!!! Prayers

My babygirl has been measuring smaller and I’ve been having ultrasounds every Friday and NST’s every Tuesday for the past couple of months. Last week they said if her head was bigger then her body I would’ve delivered then. They said she can get more nutrients outside of me then in me. I have my BPP ultrasound today and I’m just assuming that if she doesn’t move like they’d like her to, they may keep me, or if she doesn’t practice her breathing? Next Friday is when they will measure her, and if she hasn’t gained much, I will most likely deliver then. Prayers!💜 this is my first baby
