We want to expand the family!

I had the implant in my arm in May 2013 and I took it out in February 2014 and we tried to have a baby end of February and no luck. We ask the dr for advice to gives me something to in  induced the chances and nothing and nothing happened yet. Any advice on what I can do about this or who u I can see about this. I already have two kids previous to this. My husband has no kids yet.
