Feeling Down

I never had symptoms with my first pregnancy. So I had my BFP for my second on 9/11 and now all I can do is worry. Would if it was a false positive or what if something goes wrong and once we have the ultrasound the baby isn’t there. I’ve been really getting myself down today thinking about all of this. according to my app I’m 4 weeks 3 days so I know I’m early. I just want some symptoms to know that baby is there and doing ok. 😞
