2 years and no luck

Today my period started on time, like clock work every month, again. And every month for the last two years I have cried that it didn't work again. All tests come back positive, nothings wrong, I ovulate every month, I'm regular, I've had 1 baby and yet 2 years, no baby. I pray and beg that I can have this 1 righteous desire, to build my family and for some reason it's not working. I'm at a loss, angry, frustrated, sad and now don't know where to go. When you're young you're taught "don't have sex or u will get pregnant". Who knew it would be this hard as a woman in her 20's to get pregnant. I just pray one day it will happen because I can't keep "trying" every month to be disappointed again. 😓
