How to ease the thought of losing your baby?

Does anyone else worry between appts that something will happen to their baby? I haven’t heard her heart beat in 4.5 weeks because i haven’t had an appt since then, and my at home Doppler hasn’t come in yet. My appt is next week and it can’t come soon enough. I just so desperately want to hear her heartbeat and know she’s safe and sound.

My body is still “acting” pregnant- heart burn, stomach growing, boobs hurt, etc. but going this long without hearing her makes me nervous. I’m almost 17 weeks so not far enough to feel her moving.

I’m just so scared to lose her because I love her so much already. I dont know how to ease these worries. 😢
