I need support

I am 22 and have a two year old. We’ve been trying for baby number two for a couple of months and haven’t succeeded. I’m feeling really defeated. I know that others struggle for years and I don’t want to be insensitive to that but i guess I expected it to happen faster. Our first was one and done and it wasn’t serious trying but now we are tracking ovulation doing the deed multiple days I don’t know what else I can do. I think it’s just that I expected too much and now I just feel heartbroken. We decided we didn’t want a baby in the holiday season so this was our last month to try until April and I’m just so disappointed that it didn’t happen.
