Paranoid about no period after BC removal

I had my Mirena removed Jan. 4th and haven't had a period in over two years due to it. I have yet to have one and am wondering if this is what might be hindering me from getting pregnant. I have two children and was able to get pregnant very quickly. I lost my right ovary before conceiving my second son so I was surprised it happened fast with him but now wondering what's wrong. I was pregnant by now with both of my boys. I'm only 26, I don't think my age would have anything to do with it. I'm probably just paranoid, anyone else go through something similar?
