7 weeks today, first ultrasound

Lauren
Had my first ultrasound today at 7 weeks exactly. I was originally scheduled for Friday, but due to spotting over the weekend, my doctor squeezed me in today. After my miscarriage in September, I was fully prepared for the worst. 
As soon as he stuck that probe up there, I immediately saw that flicker on the screen and said "A heartbeat!" I then quickly progressed into the 'ugly cry' and my husband kept asking if I was ok... 
160 bpm and measuring at 6w2d. 
I am so thankful for this blessing. But at the same time, I feel like my anxiety is just as high. How am I going to survive this pregnancy?? I'll have a head full of grey hairs by the end of it! 👵🏼
