Yes, it used fertility friend a lot to learn about the signs of ivulation and to track my cycles. It's free. I never used the premium service.
It can also take two completely healthy people up to a year to get pregnant. I completely understand the desire to finally be pregnant and concern when it doesn't happen. Stress over the situation can delay your period and prevent ovulation. So, the best bet is to just try to relax and not stress out as hard as that may be.
