My body is useless

Try for almost 2 years now and I lost 50 lbs to combat my pcos and irregular periods.. Finally at 130 and the healthiest I’ve been in my life with regular periods for the last 6 months... now here I am 9 days late with no period symptoms and yet another negative test... as a woman wasn’t I built to make children? so why can’t I make another... as a woman I feel like my body is useless at this point 😔
