Trying to conceive

Norma
I've never been pregnant and I just started using this app to see if it will help us.  I've recently lost 60 pounds & have been told by my gyno I'm good to go and we've only recently started trying to get pregnant but I'm scared that I may not be able to conceive.  In 2 years we've never even had a "scare" although in those 2 years I've only recently had a regular period since July 2013 due to my weight loss.  Am I just being paranoid? Is there anything else I should do or can do to increase my chances of getting pregnant....
