Will an evap come up straight away??

[Charlie111]

Hi, I’ve been feeling really pregnant so I took an FRER this morning! I could see a faint line within the 3 minute period which has remained, but too faint to tell if there is colour to it.
Wondering if an evap would appear this quickly??
I also took a digital which was negative - but may be too early.

I’ve had the same problem. Following to see what others say

If it's within the 3 minute time limit more likely it's a real positive. I've gotten a line at the 3 min mark and even after and was pregnant. Usually evaps don't show up till 10 min after the test has been taken. Which test did you use? Do you know dpo you are? And digitals take longer to show. They're like 50miu.
