Guys I don’t understand.. not pregnant ?

I’m having all the symptoms I did when I was pregnant with my 2 sons! I don’t understand. Took 2 tests today and both negative .. unless it’s just too early ?

I’m having discharge , really dried out hands that itch bad (only had this when I was pregnant) back and belly pain. Peeing more. Hungry at night..

But BFN?? I don’t get it..

I’m breastfeeding my 6 month old so I have no idea when I’d be considered “late” since I never got my period back yet.

I see the faintest line if I hold the test a certain way and use my flashlight and was after the time frame for the dollar test, so I know that’s invalid. I’m just confused
