Worried

I’m 10 weeks and 1 day and I’ve had mild symptoms since day one, and they come and go. I definitely know I hit my peak at about 9.5 weeks because I actually started getting sick, but that lasted about a week and now it’s just mild nausea again. but for some reason I can’t shake this anxiety I have that something is bound to go wrong. I saw a perfect little peanut with an excellent heartbeat 5 days ago.
