My heartaches!!!

I have been ttc for 4 long years & right now I just can't stop the tears from falling down my eyes. Aunt flo just showed up & I just knew it was our month for our bfp! I guess I was wrong. My heart breaks in a million pieces just thinking that I might want ever be able to have another child especially with the loml who has no kids of his own. I'm so lost for words Idk what to do or how too move fwd. Is there anybody who has some advice that's been ttc for awhile & got a bfp who can tell me what to do? I'm willing to try anything naturally! This just can't be the end for me I'm trying so hard not to lose faith
