Just need some advice

I'm 24 and my husband and I are trying to conceive baby #2. We've only been trying for about 2 months but I'm already getting frustrated. I never see any mucus around ovulation and I'm not sure if that means anything. I don't remember seeing any last time either. I guess I just have this fear that I'll never be able to have another baby. Somebody please tell me I'm not crazy! Lol
