Ectopic Pregnancy

So I had an etooic pregnancy 2 years ago. I was 8 weeks pregnant and I didn't know since I kept bleeding thinking it was period until I got a ultra sound and found out I was taken to the emergency room asap for a etooic pregnancy. My left tube was removed. Doctors said to not worried that I was able to get pregnant with one ovary. After 2 years now I'm looking into getting pregnant. We have 6 months now and no luck!
