Fear??!

llc
Im 14w3d and had a ultrasound at 14w1d and baby was doing great had the hiccups and was moving all around. Ive had 2 MC in the past. How do i get over the fear of it happening again. Ive been a little crampy the last few days nothing serious,mild, but i cant shake the fear that something is gunna go wrong. Everything is going perfect. I do have a doppler at home but i ran out of gel and havnt bought any so that way i wouldnt use it as much but i cant help but feel something is going to go wrong, even though nothing has happened to make me feel this way.
