Just found out I'm pregnant again after miscarriage, so scared

I had a miscarriage 5 months ago at 12 weeks I lost so much blood and was very traumatic for me, had a d&c and wasn't ovulating, or so me and the doctors thought, turns out I'm pregnant again and I can't help but worry and feel like I'm just waiting on something bad to happen! So scared 😞 has anyone else felt like this?
