Usually if it's within 30 min on a first response it's +. Cheapie tests aren't reliable after 30 min though
I don't believe a false positive is likely. Positives come from detecting the hcg hormone that you get when you're pregnant. I'd still confirm with another test and make an OB appt.
I would take a digital test that way you know for sure
Sounds like u have a baby to me
Could be an evap line. That's why pregnancy tests have a time frame that you're supposed to check within. An evap line can appear after the time is up and it can appear as a positive, but not actually be a positive.
Do another test or get ur ob to do one for you that way at least you will no then
