Oh you know, just worrying 😰😭

I am currently 8w 3d and my last US was at 7w 3d (so a week ago) and everything was great! It was the first time the whole pregnancy that I've felt like I could be excited and things were going to be okay...if I decide to do the genetic testing which I am leaning towards they mentioned that they do do an US at 11w and 13w...otherwise, my next US wouldn't be until 20w 😰... I'm a FTM and obviously since I'm so early I can't feel anything, but I feel like I don't have all the same symptoms I did in the beginning (I'm not AS nauseous, my boobs aren't AS sore) I'm really just exhausted. I am terrified that something is going to happen that I don't even know about because I have to way of checking/knowing 😞 does anyone have any suggestions on how they handled this, especially if you are a worrier like me? I've debated getting a Doppler but I honestly don't think that I should...I know myself and I'm worried it would do more harm than good 😞 I have a dream almost every night that I'm bleeding 😞 I didn't realize how scared I would be of losing this baby.
