TTC baby #3

After my 2nd child in 2007 I had an IUD inserted. I thought I was done having children. Now I am in a new relationship and very happy. My husband adores my kids but he wants a child of his own. I had the IUD (paragard) removed June of last year and we have been TTC since, but nothing. I'm 30 my hubby is 27. I'm concerned that it's me. I hope we're able to get pregnant we both want this child so much. It's frustrating and I'm growing hopeless. I don't want to have to see a specialist. Anyone have any stories similar to mine that can give me hope? I'm feeling pressured to get pregnant ASAP because of my age I'm going to be 31 in May.
