So discouraged :(

I am 23 years old and have a two year old child which was a total surprise.. Me and my husband have been trying for baby number 2 for about 5 months now and nothing:(. I had figured it wouldn't take long being that my first pregnancy was a surprise but I was obviously wrong.. My periods have always been a few days off so they are not strictly always on time but I am usually not later than one week if I am late.. Do any of y'all have any suggestions for me to try?
