False positive ?

Brittany

I took a ept pregnancy test and I thought I could’ve saw a line and the same for the first response both taken last week. I forgot to trash them and found them. Looked at the ept one and it’s positive. Are ept pregnancy test known to give evap lines after time goes by? My only issue is I started stopping Friday and still am all the symptoms pointed to my AF minus the menstrual cramps. Advice please!
