Get a first response test, blue dye ones can give really bad indent lines. I did a clear blue and it came up with a blue line but it was after the time frame but only by a couple minutes and it looked similar to your picture. I would test again with maybe a pink dye and a blue just to be sure. Good luck 🤞
I once read that you’re more likely to get a false negative, than a false positive. So I would test again tomorrow, first wee of the day 👍🏼
Test one more time before your period is supposed to come
