Pregnancy Test

Naja • Rainbow baby🌈 4/19/21 🥺💗 I love you angel.

The first picture is from this morning and the last picture is from just now . It’s 11:33 pm. I took my first pregnancy test this morning around 9 Am. I got a strong positive this morning . The one from just now looks a little more faint. Is that Normal ? Should I worry?
