ttc #1 slowly giving up

It's easier said then done. It is going on 2 years since my so an I have been ttc still no luck I told myself I wouldn't buy anymore tests until I really knew in my head that I was pregnant (sounds crazy) I've been having pregnancy like symptoms an the other day my hunny told me just be pregnant already. 😟 it breaks my heart every time I test an it is a negative..My period last month was 3 days super light so I figured nope not this month..now today 20-30mins ago my mom told me she's noticed me being moody an very sensitive so she got me a test she said "I'm gonna be so excited I'll finally be a grandma" well I tested an yet it's another negative 😭💔idk if I'm testing to late in the day or if it's to early I work nights so I sleep during the day an up at night. I'm slowly loosing hope..I'm slowly giving up but I DON'T wanna give up 💔😢
