I need advice, bfn turned into a bfp or indent?

Really need some advice or just to know if anyone’s ever got a bfn that’s later showed a line and turned into their bfp?

My period is due in 5 days, and I tested yesterday morning and got nothing. I went to sleep (I work nights) then when I looked at the test after about 4/5 hours the test looks positive.

I know people say don’t look at the results after the time recommend but I just want to know does this look like it could be a bfp? I didn’t track ovulation this month because it was causing a LOT of stress and I decided that wasn’t good for me or my husband. But suspect it was somewhere between the 16th and 19th.

Thank you❤️

First test- (after nightshift at about 13.00)I didn’t drink for 5 hours before testing

And once I checked it later on-
