Had sex everyday for 2 months

Abby • Ttc my first baby.
Literally everyday, except for the days I was on my period and I'm not pregant. Could there be something wrong? Because it's not like I'm missing my ovulation day. My fiancé and myself are getting very worried :( Now on month 3 of ttc. I'll be 21 next month. AF comes every 28-35 days.
