Tesco HPT positive hours later?

[Sunflowersandrain]

My mind is in overdrive. 12 dpo and I took a Tesco home pregnancy test (blue dye and forms a cross when positive) and it was negative in the time.

Hours later I happened to notice it was a positive. Now I know blue tests are known for Evap lines but this isn’t a faint line, it’s a positive line. If it was within the 10 mins I’d be sure.

It’s a faint positive with a much darker blue on the left side of the line. Almost like an outline.

Just a question, how many of you had a positive after a positive outside the time frame?

Sorry to say but I'd consider it invalid and test with fmu tomorrow morning. In both my pregnancies, I had cheapies and they came up positive within about a minute at 9dpo.

I had this once on one of them tests a few years back. We weren't trying at the time and can't remember why I tested. Anyway it turned out to be a false positive/invalid test. I'm 100% sure it can't have been a chemical or anything like that as we later went on to be diagnosed as 100% unable to have children naturally and had ivf.

AF arrived… not this month for me
