My boyfriend and I have been trying for 9-10 months now to conceive but haven’t had any luck. I had a copper IUD previously which we took out ourselves when we decided to try having a baby of our own. Could this cause a problem?

We are young healthy adults. I am 24 and have 2 children from a previous relationship (took 3-4 months to conceive them), and he is 27 with no children.

Is there anything we can do to increase our chances before we look into seeing a doctor. Thanks!
