pregnant after miscarriage and scared

So I am finally pregnant after having a miscarriage (blighted ovum) a year ago in June....after 6 months on fertility meds, I got my positive on Oct 11th....according to glow, I'm about 6 weeks 3days. I've been praying for my rainbow and I'm so scared that when I have my scan on Nov 6th that I won't see a baby. I have barely any symptoms, which I know every pregnancy is different, and the symptoms I do have i overanalyze everything. one day my boobs hurt so bad and the next day only minimal. one day in peeing all day then the next it's back to normal. I know have minor symptoms is a blessing, but after losing a baby, I have a hard time thinking everything is alright. I'm just so scared that something is wrong
