Ruined my whole day 😞😪

I’m on day 3 of no period,so I’m 17DPO. It’s 4:15 in the morning right now because I finally thought this was it and I couldn’t even sleep..so I got up prancing to the bathroom like an idiot hoping to give my husband the best news when he got home from work for like an early Father’s Day gift....took the test,and a BFN thrown right in my face. At this point I’m over it,I feel like giving up. Should I even bother waiting another week to take another one? 😞
