Faint lines on numerous test but "pregnant" on CB digital

Sooooo I'm so confused... 

My last period was October 14/2018 so I'm currently late by a little over a week. Me and my bf are trying so hard to have a baby. I've done multiple pregnancy test. First and second day of missed period were negitive and now the past 4 days is very faint lines. Did a digital clear blue and came back pregnant 1-2 weeks. So I did another test today and again very faint line it don't seem to get much darker. I'm making a appointment for blood work today. But I need some opinions.. 

I'm having pregnancy symptoms of increased sense of smell. Feeling sick to my stomach, nipples are darkening not by much. Sweety feet. Constantly needing to urinate. 

I just want to have a baby so bad so I hope I am actually pregnant I'm just so paranoid that I'm actually not and I'm body is just playing games with me Ugh.. help
