Trying to Conceive #2 at 32

I am starting to feel discouraged and I just cant help it. All my friends that I know had their kids really young and here I am at 32 with a 4 year old trying to conceive #2 and it's not happening.

I keep asking myself why and try not to get upset but I want to give my son a sibling so bad, due to finances we couldn't afford to have 2 in daycare so we didn't try sooner. We have only been trying now going on 5 months consistently but I am scared its not going to happen. Ughhhhh.

Sorry I know there are others who could never have kids or have been trying forever but I feel like venting so here I am.
