What do you think?

So I posted a few days ago asking whether periods can be irregular 8months after birth. I’m now 9 days late according to Glow (CD41) I took a test last week that was negative but as I still haven’t got my period I tested again today. I feel like I could see a faint line on frer, I’m not on contraception but we have used condoms very carefully (to our knowledge). Do you think this is positive? Other half is going to get one for the morning as this was just taken in the afternoon today. I also tested with a cheap test that wasn’t an early detection one and it was negative but in my experience frer is usually quite good.
