5wks & stressing! Need to talk!

I was perfectly, perfect! So excited for my new little miracle and for my daughter to be big sister! Until I had to break down and tell my gma!! She said she’s excited of course! But she was like it’s early. Anything can happen......ugh great :( now I keep stressing and worrying about miscarriage or if there’s even ANYTHING growing in there!! I’ve been reading tons of google, of course. And it helps then it doesn’t!! I’ve been taking prenatal vitamins since before I got pregnant. I’m just stressing and wish there was a way to know before my confirmation due date ultrasound that there’s a perfect little bean in there!!
