ttc issues

has anyone been ttc and had all the signs that your pregnant even the cravings and found out that you were not pregnant if so please comment and let me know what you found out or what happen case we have been trying and I have taken test after test and gotten neg every time so with all the symptoms there I thought it was just another time like with my 5 yr old where I would have to go get a blood test done so I waited for my ol man to fall asleep so if it did come back pos I could surprise him and I went to the local emergency room and found out that I am not pregnant I have not had this happen before and it has never been this hard for me to get pregnant and I'm starting to feel crushed and at a loss I have an amazing man that wants to be a father and a dad to a child of his own and I feel like I can't give him anything more than his 3 step kids which don't get me wrong he loves and adores like his own it's just he knows I want more kids and wants to give me the world and was told he could not have any kids of his own and it's getting to him so I decided to try and talked him in to it and now all this has happened and the pic is of him and my 2 yr old
