Trying to conceive after second child

My fiancé and I have been trying to have a baby for about 8 months now. I have a child from a previous relationship and she is 4. After I had her, I decided to get on birth control. I went with the mirena since I loved not having to worry about missing my pill or shot. Two years into having it, I had it removed due to health issues. I've seen lawsuits about people sueing for infertile and other issues. I am praying that is not the case with my situation. Not sure if I should go to the dr now and have them check me out.
