Faint line, maybe?!

Steph

Hi everyone! We’ve been TTC for a month I’m 2 days late on my period. With VERY slight spotting. My hiccup here is on Flo it says my period is suppose to come the 28th then bounces to the 26th in a way I’m technically not late. Not sure which one to go off of. Any-who, I took a test today & there is very faint line for a positive! But I’m not sure if it’s just me bc it won’t show up on pictures & my SO can’t tell either bc again you can barely see anything. We are sort of like maybe there’s a line & maybe there isn’t. Now I’m coming to you ladies. What do you guys think? & what should I do from this point forward? Should I retake next week? Super nervous!!
