Somebody help me!! 😭😭😭

I've taken 5 pregnancy tests 3 of them have extremely faint lines I couldn't take a photo and show it because nobody would see them I took these last night. Since then I've taken a further 2 this morning first response and the same cheap one as the others from last night and those have come back negative have absolutely no idea what's going on. Also I went to the toilet and wiped and there was what looked like old blood (brown) earlier on. It can't be an evap line surely on all 3 :'(
