Not a pregnancy 😔

I been feeling off for the past couple of days so I went to go get a pregnancy test and I accidentally picked up and ovulation prediction test so when I Took the test two lines came up so I thought I was pregnant... I was so hype and couldn't wait to tell my Other half ... Later that day I told him and showed him the test and he was excited to. I woke up in the morning and went to go throw the box away but then finally look at the box and it had ovulation prediction on it 
You guys I feel so bad and down .. What should I do ?
