I feel like I'm never gonna get pregnant

I had my son when I was 20. He is 9 now. I am finally in a position to have another baby and went back to school to make our lives better. I went off birth control in August and still nothing. I started off the new year with my period. 😒 With my son it wasn't planned so I had no idea how hard it is to plan a pregnancy. Anyone else take awhile to get pregnant? Any advice on what would help make it happen?
