WTF? All evap lines or very early sensitive test??

Ok three days ago I was feeling sick to my stomach so of course I took a test. By the end of the test period I see the faintest positive line. I test again, same thing. Since I didn’t test with FMU I go to bed to retest in the morning. Next morning I test again, same thing. I dig in my drawer to find a different test brand and test with one of the .88 Walmart ones and get a negative. Decide maybe the first faints could just be too soon so wait to check again another morning. I test yesterday and get same thing. Today I repeat this process again and the lines are darker on the tiny strip than they have been however again when checking with other tests I’m getting negatives!!

I keep thinking is this brand really giving me all evap lines?? BUT I am timing it and they are popping up within the time range and this line is MUCH darker than the first faint line I saw two days ago! Has anyone had this issue in the past? I have used this brand for the last year and have not once ever seen the faintest of a line or even an evap line! I think I’m gonna talk to my PCP and see about maybe just getting a blood draw to see what’s going on. Also I have PCOS so periods are weird and so I don’t quite know what dates this may have happened if it is in fact happening! 🤞🏻🤞🏻
