4 days late

Sheila

I am 4 days late but I took a pregnancy test 2 Monday’s ago and got a negative ... should I test again? I just don’t wanna get my hopes up. My husband and I are trying for our first child. I’ve been looking at YouTube’s of videos of woman who took the same test as me and I never looked close at the test to see if there was a faint faint faint line and now I’m wondering did I miss it by not looking all close up to the stick?
