Almost 30 and never been pregnant

Kristeen
I'm almost 30. Been married, now divorced. I've never been pregnant. My ex husband and myself never actually tried to conceive, but never tried to prevent either. Now I'm with a man also almost 30 that has two young sons and we'd love to have a baby of our own. I'm worried that there's something wrong with me, but have found no actual reason I haven't gotten pregnant yet. We haven't been trying long, but I can't help but to worry. I do have sever scoliosis and have had a partial spinal fusion, which I've been told may make it a bit more difficult but not impossible. Other than that I'm healthy and already taking vitamins and all that. Any other ideas, tips, or personal stories to encourage or help lessen my worries a little would greatly be appreciated.
