Negative test turned strong positive hours later

[Mummajoy]

Hi ladies,

I’m 3 days late and have had all the pregnancy symptoms since cycle day 21, last night I took a clear blue early test which was negative
but when I woke up this morning it was a very strong positive, I know the time frame makes it invalid/ evap lines etc but it’s such a strong colour and I’m 3 days late.. has anyone else had a colour Evap line before?

I had one that looked negative in timescale then had a line 20 minutes later and I was pregnant.. overnight seems a long time though. Can you test again?

Looks like evap and these tests are well know. Try with another brand tomorrow xx

Looks a bit thin, and it was outside of the time so I would say it’s an evap and you’ll just have a later period. Test again in a few days if your period hasn’t arrived, and try to use a digital or pink dye test, these clear blue are notorious for evap lines x

Outside the window even a blue line is likely an evap sadly. Same as the PP I've found the pink dye like first response (FRER) or even the cheap dip sticks to be more accurate
