So I have not long started working night shifts. My period is 6 days late and I thought it might be the switch to nights messing things up, but I’m taking Letrozole (femara) so wasn’t sure if that’s even possible. I took this test and there is definitely a line there - it’s easier to see IRL, the picture makes it look blurry. But I’m worrying that at 6 days late if it was a positive it should be darker than that. Could it just be an evap line? Or a CP? I’m freaking out- I’ve been pregnant twice before and lost both pregnancies 😭
