Ttc but no luck

So this was my second cycle of trying and my period started. I really thought it would be this time. I always thought if I was careless anytime (not even ovulating), I would get pregnant. I know it takes years for some people, and I might just be one of those. It’s just hard because we would love a baby sooner rather than later, especially since my partner’s dad has stage 4 cancer. I just needed to vent and share my disappointment.
