Karma?

I am so ashamed to admit it but when I was 18, I'm 28 now, I lied and to my bf at the time I was pregnant and had a miscarriage. He told his friends and my friends and before I knew it it was too late to take back. I have lived with this for 10 years and I know it makes me an awful person. Now my bf of 4 years and I are TTC and I'm so worried that because I was such a terrible person and lied at 18 that we won't get to have a baby now. What is you thoughts/feelings on karma?
