Ultrasound on Friday

So I had my dating ultrasound at 11wks (will be 15wks this Friday) and dr couldn’t get the heartbeat to come up so we could hear it (you could see heart beating and baby moving so we know things were ok) and I don’t have another appointment til the end of the month. Hubby and I decided to go to an ultrasound place on Friday to see baby and find out the gender and I can’t help but be so nervous! This is our third (and last) and I’ve finally started feeling good (minus being exhausted). I just can’t help but feel worried that something is wrong with baby since I haven’t felt any movement yet and stuff. I’m sure things are fine but the unknown is getting to me!! Just had to vent 🤪 send some baby girl dust this way! We have 2 boys and would really like a little girl since this is our last chance!
