5 weeks, 2 days

I took a few tests at the beginning of the month, before my expected period and then missed that period. From the first day of my last period, I would be in my fifth week this week. My first pregnancy last year was a miscarriage, so my boyfriend and I are really excited, even though it's still early. I try not to worry but I can't help getting nervous thinking about going through miscarriage again. I have all the symptoms- nausea, gas, breast tenderness...I'm just so scared and almost want to take another test just because. My first appointment is 3/15. Looking for some words of kindness or advice to reassure me to stop worrying.
