Advice please

No judgement. My now husband and I conceived 4 years ago but we weren't ready. I had the abortion pill. We are now Ttc and it's been 9 months with no luck. I keep replaying that day I got the abortion over and over. I also keep thinking about the day I got the positive test and I would do anything to have that again. I was young and dumb at the time and now that we are ready it's not happening. I know Ttc is hard without dealing with a previous abortion so how can I stop dwelling on it and just move on😢
