Ultrasound left me in tears! 😿😭

Had my first ultrasound this morning & I'm in tears!!!!! I will never forget that experience! I literally wasn't expecting what happened! They said I had to have a full bladder & lord knows it was FULL! I was in tears cause I thought I would wet myself but in the end, I have a healthy little person growing inside of me, I am truly blessed well WE are truly blessed!!! My lil peanut has a heartbeat of 150bpm! & im 7 weeks & 1 day, glow was only off by 6 days! I'm due December 26 so Im praying for a Christmas baby!! Can anyone tell me if 150bpm a good thing??? I think she said 128 was right on it !Β
