It can take a while for the healthiest couple to get pregnant simply because everything about our bodies is working against it and we only have a small window of time in which we can get pregnant relative to the length of our cycle. What you'll want to do is try to figure out when you ovulate. There is tracking your basal body temperature (BBT), which is your temperature first thing in the morning before you do anything, or ovulation test kits. With BBT, most women experience a slight spike in temperature when they've ovulated. Our cervical mucus/discharge is different throughout our cycles as well.
