Why me 😔

What am i doing wrong? Me and my husband have been trying to have a baby since march ❤ Our bodies are in perfect health we're both taking the correct amount of vitamins daily, both doing the recommended amount of exercise, diet, blah blah blah. But absolutely no luck in falling pregnant 💔😭 Does anyone else feel this way ? 😔 It make me feel useless when people post...."Oopsy this happened" or "I accidentally fell pregnant" be happy and grateful that your lucky enough for that to happen 😔
