Prayers needed

Going into my 16 weeks ultrasound today! I was only suppose to do a Doppler but I requested for an ultrasound instead because I haven’t seen baby since 12 weeks. It’s weird how after 16 weeks when baby can be heard via Doppler, they don’t do anymore ultrasounds but how would they measure and make sure baby is growing properly? My obgyn said as long as baby has heartbeat then it means baby is growing and doing well. I just can’t help but need more reassurance with an ultrasound and see my actual baby on the screen. After two MMC, there’s never a day I don’t worry and feel scared going to my ultrasound. Everyday is always a struggle of is my baby’s heart still beating. I can’t wait till 22 weeks when I can actually feel the baby move. I have a home Doppler but it’s been hard for me to find baby now that I am farther along. I hear so many heartbeats at the same time or I’ll hear it’s heartbeat and it’ll fade away or go away! Makes me wonder if baby is just super active and moving around. I just can’t imagine losing my baby again for the 3rd time. It’s the worst nightmare to lose your baby at any stage of your pregnancy. I’m blessed with such a nice and understanding obgyn that allows me more frequent scans. She’s been thru with me two of my MMCs. Anyways hoping for a good day at my appointment!!!!
