what am I doing wrong?

Just a venting post... I've been TTC for over a year, yeah I get that some women have been trying longer then that but I'm not other women. The longer I go with seeing negative pregnancy tests the harder it gets. How am I supposed to cope with this? It's becoming almost unbearable. I had a miscarriage in February, this month I had a really strong feeling but I was wrong. Multiple negatives and my period began. It hurts more emotionally then it does physically. Why is it so easy for women not trying to get pregnant??? Ugh, I just don't understand 😭
