Baby #2

So my husband and I have been trying for about a year now but nothing has happened. The past couple months i bought an ovulation kit but i got negatives everyday. My doctor said everything is fine and I have been keeping track of my days. Im suppose to get my period either today or in the next few days. Im ready for baby #2 but am I over stressing? What am I not doing right? I have a 6 year old boy and i feel like the I am out of the loop with pregnancy stuff. Any advice??
