Hello. My Husband And I Are Trying To Have Our

Hello. My husband and I are trying to have our first child but I can't understand what my body is doing. I stopped the birth control pill last year in August. I only got my period in October last year and did not have another one until March of this year. I then got my period in April, May, and then July. As of now, I'm still waiting for my period! (And I am not pregnant.) Before I began birth control, my periods came regularly every two months. Right now, I am frustrated because even with charting and ovulating sticks, I can't figure out if and when my body is ovulating. We want a baby so badly and we've been trying for almost a year! (I'm 28 and my husband is 25) What is going on?
