What to do?

So I have used preseed before last year and I did end up pregnant a month after. But unfortunately, I had an ectopic pregnancy and had my left Fallopian tube removed. It was really rough. We started trying again a couple months ago and well, no luck. I told my husband that I want to start to try and use preseed again. He freaked out. I guess he thinks that happened due to the preseed. He said it’s as if I’m trying to rush it. That in Gods time, it will come and all this. I don’t know what to do. We both agreed to try again and he doesn’t want to use preseed...
