I'm scared

I'm 8 weeks 5 days pregnant and going for my first scan today, I'm extremely scared they will say they can't find a heart beat, I'm scared as my friend due a week before me just posted on facebook saying she went for her scan and there was no heart beat, I'm scared as my boobs aren't sore anymore I've got morning sickness though and pissing a lot, this is my first pregnancy please no nasty comments thank you
