Dont feel pregnant, help appreciated!!

Tiffany
I am 8 weeks&2days pregnant.. I've had an ultrasound and heard my baby's heartbeat! I had the sore boobs and a little nausea. It's now been 2 weeks since I've been to the doctor and my boobs are no longer sore and I don't really get nauseous!!! Now I'm freaking out that something is wrong!!! I am a very worrysome person anyways but now I just want to buy and pee on a ton of pregnancy tests just to prove to myself I'm still pregnant:(
