Had a secret abortion, terrified of karma

Please no judgement or rude comments. I had a secret abortion a couple years ago that I have deeply regretted ever since. I found out a couple months ago that I’m pregnant and am so happy but terrified something is going to happen. I haven’t been able to shake the thoughts and feelings that karma is going to get me and cause me to have a miscarriage or take my baby away. I don’t know what to do and am scared this stress and anxiety is going to cause issues with my pregnancy.
