Faint line

Samantha

I took this test yesterday morning, the second line showed up within the time frame. I took another a few hours later. A line was present on the second one. But this morning I wake up and took another test and it says negative? I’m so confused... I’m 4 days late. My boobs are extremely sore and sensitive which is rare for me. I’m not sure what to think or if this is even positive... I’ve sent the photo to everyone I know and they say yes but the first response tests said negative..... Help please.
