Just a vent

I'm really sad today. AF was supposed to come yesterday and nothing. I had severe back pain all night but I kept dreaming I got a BFP. I woke up this morning to make sure she wasn't here yet (AF) and she wasn't so I took a dollar tree pregnancy test (the one that says it's comparable to EPT) and I got a BFN. I'm just heart broken at this point. I don't understand why it's so hard. All my results came out perfect except I have one blocked Fallopian tube yet we have been trying for what feels like forever and nothing. I'm just heart broken and I feel like I can't talk to anyone.
