So nervous after eptopic..

Hey guys, how do u shake the nerves!! Currently 4w3d preg. I had surgery for a eptopic in july so am veryyy luck to have conceived after 1 cycle but i cant shake the feeling something bad is going to happen. My dr is amazing and she has done 3hcg bloods already resulting in mon(3w6d):33 wed:84 and fri (today):190. They are doubling which is an amzing sign but i FEEL like somethings going to go wrong after weve tried for 16months to get our wee blessing. If you have any positive stories to help me during this 2 week wait for a scan id love to hear them xx
