Infertility

Payton β€’ I am 22 my husband is 23. We just got married February 13 of last 2015! We have been trying for a year...πŸ™ Baby #1πŸ™
Is it normal to be so concerned about if I am fertile or not just 5 months in to trying. I stress so much wondering if we are or not...😞 do you think it could be just us not trying enough? The hearts are when we were intimate.
