Anybody else have regular periods and ttc for 6+months?

My husband and I have been TTC for 6months now. This is my first month using the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>. I've used other period tracking apps and I always start right on the predicted start date or a day after. Anyone else have regular periods and still TTC? I just get a little discouraged every month hoping it will be my month and the af comes around. Thanks for the advice in advance!
