ectopic and still not pregnant

I am so worried. I had an ectopic pregnancy Feb 2013. my husband tried for 8 months before the ectopic, I found out I was pregnant and it was taken away so quickly. not only did I lose the baby but I also had to have surgery and my left tube was removed. Feb 2015 will officially be a year since my surgery. Iv used this app since my surgery and still haven't been pregnant. have any of you had the same situation and still got pregnant? How long did it take? I'm seeking fertility treatment the 27th of this month (if my doctor allows it)
