Need some Advice

Hey ladies I just got my bfp yesterday around 5pm I took a clearblue plus and seen a line and a faint line on my supermarket cheapie test so I got a clearblue digital and it said I was pregnant 1-2 so I was really happy and because I didn't really believe it this morning I took another cheap supermarket brand test and the line was fainter so I'm really confused for some reason I don't think my FMU is strong enough but my evening wee seems to be the best time to take a pregnancy test has this happened to anyone else I'm really worried I'm having a chemical pregnancy :(
