It looks like it would have been a faint positive considering your partner thought he could see something prior to this photo being taken. I would try again tomorrow and possibly a digital too
I say try again tomorrow and check it within time frame.
Yeah, wanted to check with digital but didn’t have one at home and left it too late to get one! 🙈 Will try get one tomorrow!!
You could test again tomorrow or day after, but for me when I wasn’t sure I used a digital test that I had to confirm with no more line guessing.
