So I’m not sure what to think but last Friday I had gotten a very clear but faint positive pregnancy test, Saturday morning took another it was basically non existent faint I was super confused so Sunday comes I test again.. the line is back and a bit darker than Friday’s test. Took a test this morning and it’s back to what it looked like Saturday NOTHING
