Trying for #2!!!

I am trying for baby #2!!! We are worried since I have not been on birth control in 5 years and have not cotton pregnant that something is wrong. My Dr appts all go good. But they at one time said I had a hormone imbalance. But I've tried during my fertile window started the day I got off AF and we did the BD every other day since then and that was over a week ago. So I hope it works!!!
