Feeling hopeless

Missy👸🏾
OK so June 3rd I take a pregnancy test 2 days after my late period left. Mind u both times I found out I was pregnant I never missed a period. It would just be 3 days late. Ok so I take the test & it has a very faint line but even my bf seen the line clear as day. So 3 days later I test again still very faint. So now I have a clear blue but im so afraid to take it & its negative. Both of my other pregnancies ended in loss & we both don't wanna get our hopes up. Also we leave for a trip to las Vegas Thursday & I just wanna make sure before I go BC im going crazy waiting. Should i just wait a few weeks or keep testing?? Sorry so long but im very overwhelmed. Also with my other pregnancy I tested two days after my bleeding stopped & got a clear BFP. IM not understanding what's going on this time
