7 weeks today

Hello ladies(: I'm 7 weeks pregnant today and I'm due Sep 7th 2016😁 is anyone else due around this time? I don't get my first ultrasound until next week and I'm so anxious and nervous I just want everything to be ok(: I was in the hospital because I was so nauseous I couldn't keep anything down I was almost 6 weeks at the time and they did an ultrasound and seen the gestational sac and the yolk sac but no baby yet. Is that normal I go in next week to see the baby and hear the heartbeat🍼💕 thank you wonderful ladies(:
