Misarriage worries

Just looking for comfort reallly but i cant shake off worried feelings of having another miscarriage. Im currently 5+1 amd every morning i wake thinking its all going to end. Bit of back story, i have 1 13yr old daughter struggled ttc for 7 years after 3 previous miscarriages had 6 failed clomid cycles then 1 failed egg collection (only 2 collected neither fertalized) then 2nd cycle we collected 5 transferred our 4cb embryo which was successful. This just isnt how i want to or imagined to feel when i finally got pregnant and i dont know how to stop the self doubt xxx
