Conceiving after Paragrad Removal

My husband and I have been married for 17 years we have 2 children together my son will be 16 in Sept. and my daughter will be 12 Dec. I had the paragard since my daughter was 2 and I recently had it removed (6/5/16) without replacement with the hopes of conceiving a 3rd child. I really have baby fever ladies...my baby sister is due 7/28 my brother is due to have his first 11/21. And tons of my Friends have recently given birth. I will be 40 in Dec by the way and hubby will be 46 in November are we crazy?
