Extremely nervous

So today is a huge day for us. I am going in for an ultrasound. I am 7+3. I am hoping and praying all is well! The reason I am so nervous is October 2014, April 2015 and October 2016 we lost babies. I have been having a lot more pregnancy symptoms this time so that's helping reassure me but I'm still nervous. I need some success stories to help raise my positivity. I've only heard of one other person having multiple miscarriages and then have a healthy baby. Fingers crossed that we see a heart fluttering away. Heck at this rate I'll even take more than one! 😆
