My first ultrasound is tomorrow ...

I’m super nervous. My husband and I have tried extremely hard to conceive and after a year and half I’m finally pregnant after first <a href="https://glowing.com/glow-fertility-program">IUI</a>.. I’m 6 weeks and one day. I’m scared we won’t hear the heart or that there won’t even be one. I’m scared it stopped growing.. I’m scared it won’t even be in there! I have so many anxieties right now
