Someone reassure me please...🤷‍♀️

I am 15 weeks 5 days and I literally have no symptoms of pregnancy. My bump seems to be getting bigger but I don’t feel pregnant in the slightest. I haven’t been pregnant in almost 6 years so I am so paranoid. Someone help reassure me... I am a huge worrier. I’ve heard the heartbeat and dr tells me not to worry but here I am worrying..
