Unsure and under time pressure

I am so confused! I'm 32, dh is 39, married 10 years. Trying to decide if we should ttc. Don't want to regret not having a family, but know now is the time if we are ever going to do it. Anyone else have a similar situation? It's all I think about: should we, shouldn't we... Playing in repeat in my head like a broken record. Is our indecision a sign that we should not?
