getting very irritated

every month we ttc and each month it doesn't happen I get so flustered with my hubby like it's his fault even though I know it's not. he has never met his father which is because his mother told his dad she was pregnant and he didn't think he could have kids.... I think that's why I get so flustered with him each month it doesn't happen..but I know that it's not his fault because he has gotten me pregnant twice this year...I just lost both of them and wonder why it keeps happening...why I can't carry the baby to term.....BUT we are finishing our fertility testing soon so we will know and I can stop being so mad
