Yesterday I used these same test! I had a vvfl that night and mid day I tested again with the same test twice and it was negative. Only symptoms I have are sore boobs and fatigue.
Retest. The one test still has pink dye all throughout it did not clear like it should have. The other one I don’t see anything. If the test dye does not clear the window all the way, then it’s not a good test.
Years ago I had false positives on Walgreens brand tests it but I definitely see it on the pregmate one too i actually noticed it’s second line first so I would keep testing to see if it gets darker
