One faint positive and one negative

[Little.h1991]

hi all I wondered if someone can help me.
I did a pregnancy test at 11pm last night and there was a faint line and a dark line. I did another test at 4am this morning and this time was a straight negative so a little confused!!

Test again in a few days but use FMU. FMU is the best to use since it's the most concentrated.
