Help. Not sure!

👨🏼🧒🏽🤰🏽

Trying for our 3rd. First kiddos were surprise lol oops. But now the anticipation is real..

My predicted period is by Friday. Nothing yet. Had some brown spotting on Saturday and Sunday only. Not enough to soak a panty liner.

I took a test over excitement but only had one. So it seems negative.. But I see a faint line or am I just hoping.

Should I wait until next week if no period?
