Hi Misshell!
This could have been a thread I wrote myself not so long ago and now Im 5 weeks pregnant, the only difference is I tested after I had a day of pains (which now I defo know were implantation)
If anything my line was fainter, I then waited a full 5 days and re tested! It was so hard to wait but worthful and gave clear conformation!
Fingers crossed keep us updated xx
