Is this wrong of me...?

Is it wrong that i get angry and frustrated on here? Its bot that i get petty and i never comment on any of the posts but my fiance and i have been ttc for awhile now and AF is due soon... I get cheapy tests cuz i got tired of spending so much money on boxes of 2 tests.... Ive gotten defective tests and recently i have line eye so i see all these beautiful birth announcements... All these pregnancy announcements... All these positive tests.... Even all of these gender reveals.... And i breaks my heart.. All we want is to be blessed with a child the natural way.. We dont want any assistance getting pregnant because we are both healthy and capable of getting pregnant without the extra expensive help..... But is it wrong that i feel negativity towards all these happy people because im failing to provide a child for our own family???... I just keep failing month after month....
